חוקרים מהמכון הטכנולוגי MIT יצרו חומר עמיד בפני מים

by רונן מנדזיצקי

Water-proof

צוות חוקרים מ-MIT הצליח ליצור חומר חדש המסוגל לדחות מעליו מים בדרך שנראתה כאפשרית עד היום רק עבור צמחים וחיות בטבע. החומר מסוגל לפרק טיפות מים שנוחתות על בסיסו לחלקיקים קטנים יותר תוך זמן מינימלי, ודרך כך להעיף מעליו את חלקיקי המים טרם הספיקו לשקוע בחומר.

הישג זה התאפשר על-ידי יצירת קצוות על בסיס המשטח העשויים חלקיקים קטנים בגודל של כ-0.1 מילימטר, אלה מאפשרים את פירוק הטיפות לחלקים קטנים יותר אותם יכול החומר לדחות מעליו ביתר קלות.

השימושים בחומר החדש מגוונים והחוקרים טוענים כי זה יאפשר השארת בגדינו יבשים לפרקי זמן ארוכים יותר כאשר יורד גשם, אולם יתרון משמעותי נוסף אותו הם מציינים הוא אפשרות שהיית מטוסים בתנאי מזג אוויר קרים במיוחד יתארכו אף הם. ע”י דחיית חלקיקי המים עוד טרם יספיקו אלה להתהוות לחלקיקי קרח על-גבי מנועי המטוסים, יוכלו אלו להיות עמידים יותר בפני טמפרטורות קרות במיוחד.

כבר זכינו לראות בעבר מגוון חומרים המאפשרים דחיית מים, אך אלו דרשו מאיתנו לרסס חומרים מיוחדים על בגדים או חפצים, או להעביר תהליך מיוחד על המוצרים שנרצה “לחסן” מפני מים. החומר החדש שמציעים החוקרים מ-MIT עשוי להוות פריצת דרך בתחום דחיית המים ולספק דחיה טובה יותר של חלקיקי מים. אולם, פיתוח החומר נמצא עדיין בשלבים נסיוניים ואין לדעת מתי, אם בכלל, נתחיל לראות בגדים, מטוסים ואפילו מוצרי צריכה כמו טלפונים ומחשבים מיוצרים מחומר זה.

30 Popular DSLR Lenses Among Our Readers [November 2013]

by Darren Rowse

Two weeks back we released a list of the 13 most popular DSLRs judged according to what our readers have been buying on Amazon over the last 4 months*. Today we’re presenting you with a similar list of the most popular DSLR lenses among our readership.

As usual – Canon and Nikon lenses were by far the most popular so I’ve divided them into two lists but I’ve also included a third list of lenses from other manufacturers below.

Nikon Lenses

How NOOBS For Raspberry Pi Can Help First Time Users

by Christian Cawley
noobs-raspberry

Despite its success, there is something about the Raspberry Pi that might just put people off: until now, setting it up has not been particularly user friendly. NOOBS aims to change that! Intended for youngsters to get to grips with computing in countries where IT skills are a rarity, the Raspberry Pi has proved to be a surprisingly popular device – especially considering the relatively low specification. Setting up a Raspberry Pi isn’t difficult – however it is unnecessarily involved, requiring SD card writing software. Wouldn’t it be much easier if the tools for installing the Pi could be simply...

10 Signs you Might be a Photo Geek

by Darlene Hildebrandt

I’ve watched a few of this guy’s videos and I have to say they’re quite funny. If you can’t laugh at yourself, who can you laugh at?

This video is by DigitalRev TV, hosted by, as he puts it in his YouTube profile, “an asian dude with British accent”. He covers 10 tongue in cheek signs that you might be a photo geek if . . .

So, are you?  I’m pretty sure I am but I’m usually the last one to bring a big camera to social events, or any camera at all. So maybe I’m a recovering one? There is hope!

Have any other signs you’d add to this list? Come clean, are you a Photo Geek too? It’s okay, you’re among friends here.

Cheers,

Adobe’s Letting Everyone In On $9.99 “Bundle Deal” But Only For a Few Days

by Scott Kelby

On Wednesday Adobe announced a special “Black Friday Deal” where for a VERY limited time, they’re letting pretty much everybody in on the photographer’s $9.99 a month Photoshop/Lightroom bundle deal that was originally only for folks who owned some previous version of Photoshop (from CS3 on up), but now everybody can get in on the deal for the next few days (only until Dec 2, 2013).

When I posted this on my Facebook page, it was seen by over 140,000 people, and of course there were a ton of comments — lots of happy people taking advantage of the deal, the usual amount of mis-information, and of course we heard from the same people who aren’t happy no matter what Adobe does. I thought I’d address as many of those comments as I could here in a short Q&A. Here we go:

Q. I had the full Creative Suite, and I wasn’t able to take advantage of the $9.99 deal, but now I can?
A. Absolutely.

Q. But I called Adobe Customer service and they said I couldn’t.
A. They’re wrong. Try calling again.

Q. But what if I already subscribed to Photoshop alone? Can I downgrade to this and save the money?
A. Yup!

Q. But I called Adobe customer service and they said I’d have to pay a cancellation fee?
A. You don’t. Try calling again.

Q. But what if I never ever owned Photoshop. Can I get in on this deal?
A. Yup.

Q. Really?
A. Really!

Q. I didn’t see that one coming.
A. Me either. 

Q. What if I already have a Creative Cloud subscription that costs more?
A. They’ll let you switch to this cheaper plan as long as you do it by the cut-off date.

Q. No way!
A. Way!

Q. But I called Adobe Customer Service and they said I can’t downgrade
A. Call back until you get someone that has actually read the memo.

Q. “They must be hurting for revenue.” (direct quote from Facebook)
A. Adobe had hoped to have one million subscribers by the end of year. They hit their goal nearly four months early, and now Adobe’s stock is at an all-time high. Yeah, they’re hurting’ ;-)

Q. Should I form my opinions of how Adobe is doing financially based on a hunch or what I read from strangers in online forums, or should I actually read the official business reports?
A. Ummmmm.

Q. I heard I have to run Photoshop in a Web Browser. Is that true?
A. For the love of God, please let this one go. No. No, no, no for the millionth time no. You do NOT run Photoshop or Lightroom in a Web browser. They work just like they always did.Ugh!

Q. Yeah, but then I lose access to all my images, right?
A. You do NOT have to store your images in the cloud. Please let this one go, too!

Q. You sound like you’re frustrated.
A. For a year or so I’ve been reading the same “You have to run it in a browser”…”You have to stay connected to the internet all the time” and “you lose access to all your images”  and all this same old misinformation is just starting to wear me down. Sorry.

Q. It’s OK. I know you’ve taken a lot of heat, and we appreciate you helping to cut through the clutter [obviously not a real Facebook comment].
A. Thanks for understanding.

Q. I know Adobe says they’re going to try to keep the monthly price at this level, but they don’t guarantee it. What if it goes up?
A. My understanding is they are not planning to raise the monthly subscription rate. I imagine it’s because if they did after a year or so, they would lose a lot of customers, right? But nobody is “locked into” this thing — if they raise the price at some point down the road, you can always just not renew and go back to whatever the last version of Photoshop you owned is. That being said, just for fun let’s  pretend that they decided to raise the monthly subscription by 10% at some point. That would mean you’d have to pay (wait for it….wait for it…) $12 more a year.

I seriously doubt even that will happen, but I would pose this: find me something whose price just never goes up: Gasoline? Milk? Bread? Electricity? Coffee? College Tuition? Eggs? Anything? 

Q. Why does it cost more in the UK and in Europe?
A. I ask myself this exact same question every time I visit the UK or Europe. Why does my hotel room cost twice as much there? Why does a can of Coca Cola cost twice as much there? Why does the exact same microphone that I rent here in the US cost triple when I rent it in London? It’s the exact same mic! In fact, pretty much everything over there costs at least double of what it does here or more, even if it’s the exact same product? Why is that?

As for Adobe, they have offices in the UK and all over Europe, and staff in all those locations, and I imagine their offices cost at least double what they do here. So does their electricity, gasoline, staff salaries, insurance and of course their taxes have to be dramatically higher, and their overall cost of doing business has to be through the roof over there as well. Yet, their customers expect them to eat all those extra costs and charge the same amount that they do here. Unfortunately, that’s not generally how business works. Extra operating costs are passed on to the customers to offset the cost of doing business in that country. Just’ sayin’.

Q. What was your favorite comment over on your Facebook page?
A. This one from Robert Court

“10 bucks a month for professional software. I upgrade every 18-24 months both LR and PS. Hummmmm. So if I am doing the math correctly. $190 PS and $80 LR = $270 divided by 18 months = $15 per month. $270 divided by 24 months = 11.25 per month. So where exactly is ANYBODY being ripped off. Now they are letting everyone in on the deal even if you never owned PS. I still do not get what people are B!!ching about. I for one am all in on this deal and no I did not drink the Adobe cool-aid. This is professional software for $120 per year. Even if you are a hobbyist you should consider selling your gear if you if you can’t somehow come up with two Starbucks coffees per month. Really if someone cannot afford this PROFESSIONAL software they have bigger problems in life than Adobe. Thank you Adobe.”

It had 17 likes. :)

Q. What was your least favorite?
A. I deleted it.

Q. But that’s limiting freedom of speech!
A. It’s my Facebook page — not The Washington Post. I’m not the government. I don’t owe anybody the right to attack me, or other people who comment, or use foul language, or just plain hate on my personal Facebook page. If you want freedom of speech, you can go start your own Facebook page at this address: http://www.facebook.com (sign up today!).

Q. Should people who aren’t going to take Adobe up on this offer take their time to tell you that in the comments?
A. Sure. It’s fun. They are dying to tell me, yet again for the millionth time, that no matter what deal Adobe comes up with they’re not going to get on board. They think I somehow have control over the pricing policies of a multi-billion dollar global software company. It’s kinda entertaining at this point. 

Q. So, is Adobe going to switch back to selling the latest version of Photoshop?
A. No.

Q. Are you sure?
A. I’m more sure about that than anything else I’ve written on this page.

Q. Any other comments from your Facebook page that stand out?
A. How about this one from Armando Almada responding to Robert’s comment above:

…totally agree….a glass of wine in NYC is $12, and that’s no include the tips….

I also like this one telling “The other side of the story” from Karl Mathias Moberg who wrote:

Totally agree with this. As a part-time photographer, with not a very high income… I can’t afford the upfront cost for both photoshop and lightroom. This, and the normal CC deals are perfect for me. I have no problems what so ever with the subsciption models.

A lot of folks want to pretend that people like Karl just don’t exist. The fact is, there are a ton of people who can now use Photoshop and Lightroom that were locked out because they didn’t have $849 (the cost of Photoshop and Lightroom last year, and the only way to use it was to buy it at that price).

Q. So, what if I don’t sign up for this by December 2nd, 2013? Then what?
A. You don’t get the deal. That’s it. It’s a limited time offer (it’s a Black Friday Deal running before and after black Friday but not by much).

Q. Where can I learn more?
A. You can get the official details direct from Adobe’s deal page. Here’s the link. They also have an FAQ here.

Q. OK, if I don’t like this deal, or I live in Europe, or I live in Russia where this deal isn’t even valid, or I had a fight with my spouse, or I’m just generally angry, can I blame  any part of Adobe’s Black Friday Deal that I don’t agree with on you?
A. What the heck  —- sure. Why not? :)

OK, that’s the scoop as best as I know it, and of course as always I reserve the right to be totally wrong about any or all of this. Here’s wishing you a day where all your pixels move right where you want ‘em to.

Best,

-Scott

P.S. No football this weekend but I am shooting a wedding tomorrow in Orlando and hopefully I’ll have some shots to share here early next week.

Carl Zeiss Distagon T* Otus 1,4/55 ZF.2 and Sigma 18-35mm f/1.8 DC HSM A lenses tested at DxOmark

by [NR] admin

Zeiss-OTUS-55mm-f1.4-APO-Distagon-T-ZF.2-lens
Carl Zeiss Distagon T* Otus 1,4:55 ZF.2 test results
It's official - the Carl Zeiss Distagon T* Otus 1,4/55 ZF.2 lens ($3990) is currently the best lens available for Nikon F mount according to DxOMark:

"With outstanding optical quality, the Carl Zeiss Otus 1,4/55 certainly represents a high water mark for a retrofocus fast standard for DSLRs. However, it might not be the high price that deters people, in practical terms the large size and lack of autofocus may be the more limiting aspects, but there’s no denying optical quality like this demands attention."

Here are few other comparisons with similar F-mount lenses:

Best 50mm lens for Nikon
Best 50mm lens
Best 50mm f1.4 lens

DxoMark released their test results for the Sigma 18-35mm f/1.8 DC HSM A ($799) lenses:

וידאו: צפו בגב ה-LG G Flex "מרפא" עצמו תוך 2 דקות

by אוהד צדוק

g-flexסמארטפון ה-LG G Flex הצליח למשוך המון תשומת לב בגלל היותו השני בעולם עם מסך גמיש, אמנם צורתו הקעורה העלתה חשש לגבי עמידותו. וידאו חדש שמעלה LG לערוץ היוטיוב שלה מציג את ה-G Flex עובר סדרת עינויים המראה לנו כמה המסך באמת גמיש ואיך גב המכשיר "מרפא" את עצמו במהירות.

רבים, וגם אנחנו בינהם, לא ממש הבינו מה זה בכלל אומר שגב ה-LG G Flex יכול "לרפא" את עצמו. הוידאו מציג מבחן של יכולת זו באמצעות מברשת נחושת השורטת את גב המכשיר לעומת גב סטנדרטי אחר. שמים לב די בקלות שגב ה-G Flex לא נשרט כמעט וגם השריטות המעטות שקיבל נעלמות אחרי 2 דקות. טכנולוגיה מאוד מעניינת שאנחנו מקווים שנראה אותה משולבת במכשירים נוספים, במיוחד בגלל העובדה שהיא שומרת על מראה חדש של המכשיר.

לחץ כאן לצפיה בוידאו

הבדיקה השנייה בוידאו מתמקדת בגמישות המסך של ה-LG G Flex. הוא אולי בעל צורה קבוע, אבל אם תשבו על המכשיר או תפעילו לחץ כלשהו על גבו הוא לא ישבר למרות צורתו הקעורה. המסך עדיין מספיק גמיש כדי לספוג את הלחץ ואין סיבה לחשש כפי שניתן לראות במבחן המשקולות שהוא עבר. זה בדיוק מה שב-LG הבטיחו עם טכנולוגיית המסכים הגמישים – אולי לא יהיה ניתן לשנות את צורת המכשיר, אבל יהיה קשה מאוד לשבור את המסך.

Goodbye, PC. Hello, Cloud.

by Matthew Guay

The PC isn’t dead — far from it, really — but it’s far from the most exciting thing these days. The best selling deices are mobile, and when they’re not tablets and smartphones they’re ultra-thin laptops that put the priority on battery life and portability over power. There’s apps for almost everything, and even if all you’ve got is a browser, there’s a web app for almost everything as well. It’s been a long time since it was an absolute necessity to buy a copy of Office to write a document or throw together a simple spreadsheet.

And yet, there’s still plenty of things that you’re apt to need a traditional computer for. Yes, you still might need a full copy of Office from time to time, and rendering a video might be rather slow from your tablet. Perhaps you’ll want to compile software, or crunch some numbers in Mathematica. For that and more — well, actually, all you need is the cloud.

The Cloud: Your New PC.

Screen Shot 2013-11-15 at 9.19.02 PM

It’s not too uncommon to keep an old PC around to run old software, or perhaps to reconfigure as a Linux home server. Or you can get more out of your one computer by installing other OSes in virtual machines, or dual-booting your computer. All of these are great options.

And yet, none of them are precisely simple or elegant. There’s a reason most of us don’t run our own servers to host our websites — it’s easier to pay someone else to maintain hardware and keep everything running 24/7, and only have to think about our site itself.

So why not do the same for everything else? Instead of installing Ubuntu in VMware on your laptop for software development, you can spin up a VPS and SSH in. And, if you use a service like DigitalOcean or Amazon EC2, you’ll just pay for the exact amount of time you’re using the VPS, so it’s reasonable to make a new VPS to try out something new — say, the new Ghost CMS — then delete it when you’re done testing. You could even use it as a full-time Linux computer if you wanted, something developer Mark O’Connor did with a Linode VPS so he could use his iPad as his only computer.

workspaces_windows_desktop_1

The same now works for Windows apps, thanks to Amazon’s new WorkSpaces, just announced this week. It’s essentially a hosted copy of Windows 7 (actually, Server 2008, but it works the same) and 3.75Gb of ram to tackle any Windows-based task you want for $35/month — or $50/month if you include a full copy of Office 2010 Professional, though you could just go for the cheaper one and throw in Office 365 for an extra $9/month on your own. And it’s everything you’d expect: you can download and install practically any Windows app you want, and run it in the cloud. Want to run Visual Studio, Mathematica, or even a Flash video from a site in Internet Explorer on your iPad? No problem at all — Windows is now just another web app.

Amazon’s obviously not the first to offer hosted Windows — Nivio gained popularity last year for offering something similar aimed directly at iPad use, but it doesn’t appear to be around today. Many others have offered similar services, and then disappeared. It’s a hard, low margin business, but Amazon’s already experienced at the hosting market, and it’s hard to imagine them offering this and shutting it down soon. This time, the PC in the cloud actually makes sense.

See, when you’re using a web app or a hosted operating system in a VPS, essentially you’re doing the same thing: you’re using your browser to tap into computing power on someone else’s computer. Gmail’s always running on Google’s servers, caching your emails, sorting out spam, and pushing messages to your devices. And now Windows or Linux apps of your choice — or even Mac apps with a tad more expense and a service like MacMiniColo — can hum along just fine in a server, so the device you’re carrying around doesn’t have to do the heavy lifting. And, of all things, it’s more accessible than apps installed on your old PC back home, since your new cloudified PC apps are in a virtual computer online you can access from anywhere — or, if you wanted, share with others. It’s thin-client computing, reinvented for modern computers that do run their own apps, but can also access remote apps from the cloud.

Putting the Cloud to Work

Screen Shot 2013-11-15 at 9.27.13 PM

There’s all kinds of ways you can put it to use, most interestingly in ways that let you run software you couldn’t otherwise (yup, legacy Windows apps on any computer) or tap computing power that you otherwise couldn’t afford (witness the universities already using Amazon EC2 computing power for research projects). That power of servers-for-rent can make apps accessible to everyone that otherwise would be restricted to only the very largest of corporations, too. That’s how Pixar can offer their Renderman on Demand service through Windows Azure cloud, and how IBM is now planning to offer Watson’s computing smarts through the cloud — something your business might be able to afford for a few hours a month, perhaps, but likely not something most businesses could otherwise have ever afforded if they had to buy a Watson server and run it locally.

You can use remote servers to do insanely advanced things — or you can just use it to get your legacy Windows software running without having to maintain a PC. And, another browser window over, you can keep collaborating away in Google Docs as you’ve grown accustomed to already.

רכישה שנייה בישראל: אפל רוכשת את PrimeSense ב-345 מיליון דולר

by מידן אדרי

Apple-Store-NYC-main

לאחר שרכשה את חברת אנוביט (Anobit) הישראלית בשנה שעברה מבצעת חברת אפל רכישה שניה בישראל, כך עולה מדיווח שהגיע הבוקר (א') מעיתון כלכליסט. הפעם, מדובר בחברת הסטארטאפ הישראלית פריימסנס (PrimeSense), שפיתחה מערכת משולבת חומרה ותוכנה עליה מבוסס בקר תנועה המשמש כחיישן תלת־ממדי. החיישן מסוגל לזהות תנועות גוף ופנים ולתרגם אותם לסימולוציה ממוחשבת.

על פי הדיווח ,מגעים ראשונים נעשו בין שתי החברות עוד בחודש יולי האחרון, כאשר בכירים באפל ביצעו ביקור חשאי בבסיס החברה הישראלית ברמת החייל והתרשמו מהטכנולוגיה. המגעים הבשילו לכדי לעסקה ממשית על סך 345 מיליון דולר, והודעה רשמית על העסקה עתידה להתפרסם כבר בשבועות הקרובים.

פנינו לחברת פריימסנס בניסיון ללמוד עוד על נושא הרכישה ונתקלנו בהבעת הסתייגות מסויימת מהסיפור, דרכה טוענת החברה כי הידיעה המקורית שהתפרסמה בכלכליסט, כמו גם זו שהגיעה בחודש יולי הינה בגדר "שמועות ממוחזרות". לפניכם התגובה המקורית (מתורגמת) כפי שנשלחה למערכת גאדג'טי:

"לפריימסנס הטכנולוגיה המובילה כיום בשוק ה-3D. אנו מתמקדים בבניית חברה משגשגת תוך הבאת חיישני ה-3D וביצוע אינטראקציה טבעית לקהל הרחב במגוון שווקים כמו הסלון האינטראקטיבי והמכשירים הניידים. אנו לא מספקים תגובות בנוגע למה שעושים שותפינו, לקוחותינו או לקוחות פוטנציאלים של החברה ולא מתייחסים לשמועות ושמועות ממוחזרות."

אפל בעקבות מיקרוסופט בקרב על הסלון הביתי

אפל היא לא הראשונה שעתידה להתעטר בחיישן תנועה מתקדם, ענקית התוכנה מיקרוסופט עשתה זאת לפניה כאשר הציגה את בקר התנועה Kinect עבור קונסולת המשחקים Xbox בשנת 2009, זה התבסס על הטכנולוגיה של חברת פיימסנס עצמה. במרוצות השנים, שיפרה מיקרוסופט את בקר התנועה ואף רכשה ב-2011 את חברת Canseta העוסקת בתחום. לאחרונה הציגה החברה גרסה משופרת של חיישן הקינקט שיגיע בבאנדליחד עם קונסולת המשחקים החדשה Xbox One.

סברה הגיונית היא שהרכש הישראלי החדש הוא צעד נוסף בדרך להשקה של טלוויזיה מתוצרת אפל, כזו אשר תישא גרסא כלשהיא של מערכת ההפעלה iOS ותעשה שימוש בבקר תנועה חדש או במוצריה הקיימים והעתידיים של אפל שיעזרו בטכנולוגיה של חברת פריימסנס.

בימים אלה מתחולל קרב ענקים על הסלון הביתי בין שתי יצרניות קונסולות המשחקים המובילות, סוני ומיקרוסופט. אפל, שנוכחותה בסלון הביתי מסתכמת במכשיר ה-Apple TV, יכולה להפיק ערך רב מהשקת טלויזיה חכמה בפורמט חדש, זה עשוי לשלב גם אלמנטים של קונסולת משחקים. יחד עם הטכנולוגיה של פריימסנס, תוכל אפל לזנק קדימה בתחום המשחקים על המסך הגדול, אלו ייתמכו ע"י חברות המשחקים אשר כבר היום מפתחות עבור פלטפורמת ה-iOS של אפל על האייפון והאייפד.

לאחר רכישתה של חברת אנוביט הישראלית הפכה אפל במהירות למעורבת מרכזית בתחום ההייטק בארץ. אפל מונה כיום שלושה מרכזי פיתוח בארץ המעסיקים 400-300 עובדים. באם תתברר הידיעה כנכונה, נשלח כבר עתה את ברכתנו לחברות אפל ו-PrimeSense הישראלית על הרכישה החדשה, ובתקווה כי שותפות שכזו תוליד עבור כולנו מוצרים מעניינים ותחרותיות גדולה יותר.

Can You Tell The Difference Between a $100 Lens and a $1600 Lens?

by Trevor Dayley

One of the most popular lens lengths on the market is the 50mm. As a Canon shooter I have a few different choices to pick from at that length, but the three most popular seem to be the 50mm 1.8, 50mm 1.4 and 50mm 1.2. While on a shoot last week I decided to play with all three lenses and shoot a few photos to see how different each lens was from each other. Here are my results. [more]

Gramohorn II amplifies your HTC One in a retro-style

by Mark Wilson

Gramohorn II amplifies your HTC One retro-style

Phones are great for music, but in most cases the built in speakers are a bit subpar; quality might be decent enough, but if you're looking for a punch of volume, speakers are going to be needed. Or maybe not. If you're an HTC One owner looking for something a little different -- and have a wad of spare cash lying around -- the Gramohorn II could just be of interest. It brings not one, but two gramophone inspired horns to amplify your music without the need for power.

3D printing is all the rage, and the Gramohorn II is the latest accessory to be produced in this way. There are plaster- and metal-based versions available, but whichever one you opt for, you're going to need to have deep pockets. The plaster-based model is the cheaper of the two, but "cheaper" is very much a relative term. There are 22 color choices and five metallic finishes but only 100 will be produced.

There's a bit of a wait -- 3-4 weeks from ordering -- but if you're quick, there's still time to get one for Christmas. What's that? Oh, the price? Yeah… it's quite an expensive stocking-stuffer. This double horned beauty will set you back £999 (around $1,600). If you happen to be in the mood for spending even more money, the metal-based version could be what you're looking for.

Again this is 3D printed, but this time it is with a bronze-infused stainless steel powder. Gold, silver and bronze finishes are available, but there are only ten of each. There probably won't be too many people standing in line in front of you though, as the price tag is an eye watering £4,999 (a shade over $8,000). The horn is only available for the HTC One and only amplifies volume by up to 50 percent -- but it'll certainly be a talking point for guests!

The Path to Better Photography

by Guest Contributor

Ed Verosky is a professional photographer and author based in New York. In this article, Ed presents his recommended path to learning photography. This, along with his eBooks on the subject, have greatly improved the skills of thousands of photographers. To learn more about improving your photography, visit his site and check out his extensive eBook collection (currently 62% off at SnapnDeals).

If you’ve ever wanted a little guidance when it comes to learning photography from top to bottom, this DPS post is for you! There’s a lot of information out there, and tons of books, tutorials, workshops, etc. to learn from. But it’s not always easy to know where to start, or where you should focus your efforts when it comes to really improving your knowledge of the art and craft of photography. With that in mind, here’s a "learning road map" I’ve put together for you that has helped many of my readers. I hope it helps you with your quest to become a better photographer.

NewImage

Getting Started

First of all, I want to thank you for taking the time to read this. You’re probably looking at this right now, excited about the possibility that you might actually learn something new, something that will elevate you as a photographer in some way. Whether you are a beginning photographer, or someone who’s been at this for a few years, you probably have the desire to improve on this thing that you love.

Photography means something special to you; it’s a kind of magic that allows you to express yourself. It’s your way of communicating and sharing with the world. Whether you’re doing what you love to earn extra income, or simply for the pure excitement and enjoyment of it, that’s reason enough to want to keep improving and learning and growing. It’s not only the technical skills, but the psychology and artistic sensibility of what we do as photographers that keeps us constantly in the need to learn and adapt to everything from new gear, to new people/clients, to our own ways of expressing ourselves.

How to Use this Post as a Guide

Print this post out. It’s your guide and starting point. It can serve as a road map to learning the basics of photography, helping you to build a solid foundation from which to grow and become really good at what you do. I encourage you to use this road map and seek out multiple resources, like DPS, to further your understanding of each topic that follows. My blog, newsletter, video tutorials, and ebooks will also definitely help you learn about these things quickly and in great detail. But I routinely direct people to outside resources as well, because I think it’s important to learn from more than one teacher in order to really drive home the knowledge and principles of photography.

I’m very excited about this journey you’re on, and it’s my goal to do everything in my power to help you get everything you want out of your photography. I’m obsessed with teaching and demonstrating what I’ve learned and all the new things I continue to learn. I’m sincerely happy that I have another person I can share this excitement with right now. That’s you!

Now, we’ll begin our discussion of the four topics that I feel are most important in your development as a good photographer: the camera, the lighting, the subject, and post-processing.

The Camera

The first part of becoming a complete photographer is knowing how your camera works, inside and out. Your camera is the main mode of communication between you and the outside world as a photographer. Like your voice, your photographic vocabulary is extremely limited without some good understanding of how best to tell a story. Put the effort into learning everything about your camera and and it will pay off, big time. Plus, you’ll be able to speak intelligently about your craft, and be able to ask the right questions when it comes to the topic of lighting. The camera and the lighting; knowledge of one topic supports an understanding of the other, so you need both. Start with your camera.

NewImage

Good resources will provide numerous visual examples to help you understand how exposure works. The sequences above are just a few that I use in my eBooks to illustrate the interdependent nature of exposure controls on the camera.

———————–

Here are some of the most important things you should learn about:

  • Raw and JPEG. The differences between Raw and JPEG file formats. Learn what the differences are and why one is not always better than the other. For example, I strongly recommend that people shoot in the largest Raw format their cameras produce. But that’s not always the practical choice, nor is it always necessary. In general, however, Raw will provide you with the highest quality file from which to work with. From there, you can export out to fine-tuned JPEGs that are sure to produce prints and web display images of excellent quality. But this isn’t the whole story, and you should probably investigate what these file formats are capable of, and how they work with your post-processing software, so you can make the most informed decisions according to the demands and limitations of your schedule, software, and client needs.
  • ISO, Aperture, and Shutter Speed. These are the fundamental components of exposure and a huge topic for photographers. Our cameras are able to keep these three components in check for us in automatic shooting modes, but the auto-metering and exposure mechanisms don’t always get it right. Understanding exactly how ISO, aperture, and shutter speed interrelate will give you complete control over exactly how your exposures turn out. You need to understand this topic in order to make educated decisions about how to adjust exposure even when using automatic shooting modes. There are shortcuts to learn, too. But I cannot stress how important it is to get a real, rock-solid, understanding of exposure.
  • How to do the math of photography. It’s easy once you get the hang of it, and it’s an essential part of working with all aspects of exposure and lighting. What is this "math" all about? Well, it comes down to how light is measured in photography; we talk about light in terms of "stops" which are traditionally full increments of camera and lighting adjustments. Each stop either doubles or halves the amount of light you’re working with. For example, when working with apertures (often talked about in terms of f-stops), moving from one full f-stop of say, f/5.6 to f/8.0 cuts the light entering the camera by half. Likewise, changing your shutter speed from 1/500 sec. to 1/250 sec. allows twice as much light to expose the camera sensor. ISO works the same way; ISO 200 makes your sensor twice as sensitive to the light hitting it as ISO 100. Lighting has a similar math with a few good rules you can follow. Knowing all of this and putting it to use will put you in complete control of your lighting and exposure.
  • White Balance. Light comes in many different colors, even when it looks white to your eyes, a light source can reproduce as blue, green, or orange. Learn how to control and fix it both in-camera and during post-processing. When you’re using different types of light sources together like flash and household incandescent lamps, you’ll have to make some decisions about how to handle the difference in light color, if at all.
  • Shooting modes. Which camera mode do you typically shoot in? There are several to choose from including full automatic, program, aperture priority and shutter priority. There’s also manual mode which is very important to know how to use. In fact, for studio-type lighting, manual mode is usually the best choice. Learn what each camera shooting mode does. Each one has a real purpose and knowing how to choose the right one is crucial.
  • Manual mode. Understand how to use it and gain total control over every aspect of exposure. No, you don’t have to shoot in manual mode all the time to be considered a "real" photographer, but for many situations, knowing how to use your camera in manual mode will save you from disaster. Manual mode is also important in studio work and anytime shooting conditions require you to do the thinking when your camera’s auto modes aren’t cutting it.
  • Understand all the metering, focusing, and drive modes on your camera. It’s easy to find one thing that works and simply stick to it. But sometimes you need to switch things up to get better results as conditions change. Learning what your camera’s capabilities are is going to come in handy.
  • Evaluate and fix your shots. Know how to most effectively use all the tools available on your camera to properly evaluate and adjust your exposures as you’re shooting.

Ok, remember the broad list of things you need to learn: camera, lighting, subject, and post-processing? Well the list above is just the CAMERA part! Trust me, I know that part alone can seem overwhelming, and that’s why most people never bother to learn it all. That’s a real shame, because it’s the first part of becoming a complete photographer; you need to know everything about how your camera works.

Fortunately, you don’t need to know everything from the start. If you’re using your camera in a way that’s working for you right now, keep doing that. There’s no reason to give that up. But in the meantime, start building on your current understanding and usage of the camera and learn a little bit more as the weeks go on. Soon, everything’s going to start coming together and you’ll find that you have a total command of the camera. That’s the goal. Read the best resources on using your DSLR, and just commit to wanting it. It’s going to happen, I promise!

Lighting

Although setting your camera to one of the auto exposure modes is a great way to solve the immediate problem of getting a properly exposed image, it won’t solve your lighting concerns, and it’s your lighting that really makes the difference. Many photographers soon realize that what separates their images from better work is the application of good lighting techniques and different types of lighting sources. I would say that the ability to skillfully use lighting is the number one technical skill a photographer should seek to acquire in order to produce good work. Unfortunately, this is also the number one place photographers tend to drop the ball.

NewImage

Learning how to control your light will allow you to easily create effects like overpowering daylight (above). Here, the right combination of camera settings and flash power create a nighttime effect, even though there is actually bright window light coming into the studio.

———————–

Sure, lighting isn’t easy at first, and maybe that’s why so many photographers just give up on learning how to do it properly. It takes time, experimentation, and a good teacher to help you get to where you need to go with photographic lighting. Good books and tutorials can help you with that. When I teach, my goal is to show readers how to use natural, constant, and flash lighting in a way that really gives them a handle on it quickly.

In order to really master lighting for photography, you should learn the following things:

  • How light actually behaves. By learning the properties of light, you can easily control the way it can be directed, redirected, and modified to suit your needs.
  • How light is measured in photography. There’s a very easy and powerful math to photographic lighting (which I touched on earlier). It’s been around for a long time and has served photographers well. Learning how to measure light is crucial to good lighting and good exposures.
  • How to use strobe/flash lighting. This is one of the most powerful and convenient types of lighting you can learn to use. Knowing how to use both on-camera and off-camera flash is what separates many photographers. While it’s ok to feel comfortable being a "natural light only" photographer, it’s also limiting.
  • Lighting for portraiture. Using your knowledge of lighting will transform your portraiture work to a new level. There are five important lighting patterns you should absolutely know. Starting with a single light source, you can apply these patterns and build upon them to eventually create portraits that take advantage of multiple lights.
  • Mixing and matching light sources. Make sure to understand how different light sources (although many appear to look white to your eyes) will cause major color shifts in your exposures. You can handle these problems in-camera with good white balance techniques and also during post-processing.

The Subject

I believe in teaching portraiture in a semi-traditional way; instructing on the fundamentals and quickly moving to a more freestyle approach. An appreciation for traditional lighting patterns and contemporary portraiture will give you a good foundation for all of your portraiture work. But in today’s marketplace, the old traditional portraiture isn’t the only game in town. Working photographers should look beyond typical portraiture to find ways to differentiate themselves from others. One of the main things I like to stress is that you should start thinking about unconventional posing, directing, lighting, etc. eventually developing your own style.

NewImage

Great subjects can inspire you to get creative with your posing and lighting techniques. This type of experimentation will help you develop your own unique style.

———————–

Again, this all begins with really knowing the fundamentals of lighting, and getting very comfortable with your gear so it becomes an extension of your vision and not something that gets in the way of the creative flow. But simply knowing how to use the tools and basic techniques of your craft isn’t enough. You need to let go of the things that hold you back from creating your best work and explore new ways to look at and create portraiture. Yes, the soft skills like working with subjects and clients are important which is why it’s one of my favorite things to teach.

Here are some of the most important themes and topics I tend to discuss on a regular basis:

  • Classic Lighting. The basic traditional lighting patterns are classics and always look great. Even if you’re the type of photographer who doesn’t like to do things the traditional way, get to know the classics because they come in handy and the principles they’re based upon apply to ALL types and styles of lighting.
  • Creative Lighting. I strongly encourage you to go nontraditional, too. Working with your subjects in a way that encourages creativity includes bending and breaking the rules of traditional lighting.
  • Developing Your Own Style. It’s imperative for working photographers to do this in order not to drown in a sea of competition where so many are producing work absent of any unique style or vision. Amateurs have even more reason to explore the artistic areas of portraiture since it is a part of the amateur heritage to do so, and also because they don’t have the burden of producing work according to the tastes and needs of paying clients. When I talk about developing your own style, I don’t necessarily mean that you can, or should attempt, to do it deliberately. I don’t think you can create a true style as much as you can identify it by looking back at your work as time goes on. But in the meantime, take this as a cue to work in a way that is your own.
  • Portraiture Projects. One of the best ways to expand your body of work, as well as come up with new imagery that you otherwise might not have thought of, is to start a photo art project. Starting with just a simple idea or theme, you might find yourself discovering many different ways to express it. Even a very general concept has a tendency to build on itself as it becomes, at the same time, more defined and diverse. This process of creation and discovery can only enhance your artistic vision and technique.
  • How to Find Great Subjects. Good models are everywhere, you just have to know how to find them. This is another thing I talk about in my books, but the main message here is that family, friends, and strangers can all make great subjects. You don’t always have to look to "model" directory websites to find great people to photograph. I’ve gotten some of my best results through other means.
  • How to Direct Your Subjects. Whether your portrait subject is a client or a collaborator in your next artistic vision, it’s very important to get them excited and on-board with your ideas for the shoot. They are the actor in your drama, the star of your movie, even if your "theater" is only an ad-hoc studio setup, your subject’s confidence and enthusiasm are key ingredients for a successful shoot.
  • Make Your Work Personal. This is very important. No matter what, or who, you photograph, if you invest something personally in your efforts, it will show. Your work will be less generic and more substantive. It’s often said that all portraits are really self-portraits. While it’s not always that evident, the truth is that the best portraits happen when you recognize something special as you click the shutter. And what you recognize most often comes from a very personal place.

Post-Processing

It can be argued that post-processing happens the moment a digital camera processes the data off the sensor, and certainly when a file is converted, via some programmer’s algorithm, for view in a RAW conversion engine common in most digital workflows. Why not make the absolute most of the tools available to you, just as photographers have always done? It used to be darkroom tools, like various ways of developing film and selectively exposing photographic paper during the printing process, which allowed the photographer to enhance or correct problems with an original negative. Now it’s digital. Of course you can ruin any photograph with overdone effects or cheesy gimmicks. But used thoughtfully, post-processing techniques can help make a good picture an outstanding one.

NewImage

  • Raw Conversion Software. I recommend that you learn how to use Raw conversion software which powers and comes built-in to Adobe’s Photoshop and Lightroom products. Working with Raw files has gotten to be a rather seamless part of the normal workflow.
  • Image Editing. Software like Lightroom and Aperture make organizing and basic editing a breeze. Adobe Photoshop is the standard professional editing (retouching) tool of choice, however, the less expensive Photoshop Elements might have just enough features to allow you to do the type of post-processing you’re interested in.

Try out these products for free by clicking on the following links. You should see a "Trial" link on each product’s information page:

Of course there are also other fun and effective ways to post-process your images, including using some popular mobile device apps. This is one of my favorite topics to cover as I’m a big fan of iPhone photography and mixing DSLR photography with phone photography editing and sharing technologies.

Some of the things you might be interested in learning include:

  • Retouching. Using Photoshop tools like the clone tool, liquify, and healing tools to remove blemishes, tighten up body parts, and otherwise improve the overall look of your portrait subjects. "Photoshopping," "airbrushing," or retouching is so prevalent these days, it’s almost expected that you offer this to paying clients as part of the service. You can learn to do at least the basics by watching a few tutorial videos on YouTube, but I suggest you also invest in some basic detailed instruction from books like the popular ones by Martin Evening. Once you get that under your belt, you’ll be ready to tackle more advanced topics.
  • Effects. There are several effects that are popular with photographers these days, including texturing, compositing, and alternative color processing and black and white conversions. Some effects can be purchased as presets and actions making them simple to apply. However, I recommend you also learn how to create and manipulate images directly so you’ll know exactly how to get the looks you want and make them unique.
  • Image Preparation. You’ll also want to know the best ways to prepare your images for use in various applications like prints of specific sizes, on-line web galleries, distribution and presentation on the web, etc. Knowing the ins-and-outs of image resolution and quality settings will help you make the most of your photography. After all, what good is all the work you’ve done up to this point if you don’t know how to best present your images in the end?

This Is Just The Start

I realize there’s a lot of information in this post. At the same time, it’s not complete, just one general outline based on my experience and teaching methods. But I strongly encourage you to find your place on this map and start navigating your way through it. It will take some time, but that’s one of the best things about photography, the discovery.

All Male Motorcycle Dealership Mocks Adverts With Their Own Sexy Photoshoot

It’s not too uncommon for an automotive dealership to hire a gorgeous female model in a bikini to grab the attention of onlookers and potential buyers. MotoCorsa in Portland, Oregon decided to do just that, however, after shooting, the male staff decided that they could do it better. The recreations of each photo are hilarious. [more]

הצעת חוק ניטרליות רשתות תקשורת אושרה בקריאה ראשונה בכנסת

מליאת הכנסת אישרה היום (ג') בקריאה ראשונה את הצעת חוק "ניטרליות רשתות תקשורת", לפיו יאסור משרד התקשורת על ספקי אינטרנט, חברות תקשורת קוויות וחברות השידורים הרב-ערוציים, להגביל או לחסום בדרך כלשהי יישומים או אפליקציות בהם עושה הלקוח שימוש, כמו גם תנועה המועברת ברשת שלהם ו\או ציוד תקשורת המתחבר לרשת התקשורת שלהם.

הצעת החוק מגיעה לאחר קביעת משרד התקשורת מחודש ספטמבר 2012 כי חסימת או הגבלת WiFi Hotspot (נקודת גישה אישית) הינה עבירה על החוק. ההתייחסות הקודמת של משרד התקשורת לנושא הגיעה לאחר תלונות כנגד ספקית הסלולר אורנג' וחברת הכבלים HOT, אשר ביצעו בעבר חסימות והגבלות שונות שנגדו את עקרון "ניטרליות הרשת".

לקראת כניסתן של שחקניות תוכן חדשות ושידורים מבוססי אינטרנט, הנחה שר התקשורת גלעד ארדן להרחיב את עקרון הניטרליות ברשת גם לגורמים נוספים הפועלים בשוק התקשורת, לרבות ספקיות הגישה לאינטרנט, חברות התשתית וחברות השידורים הרב-ערוציים באופן שיבטיח וימנע יכולת חסימת שירותים בעתיד, מצד בעלות התשתית, כפי שקרה בעבר בתחום הסלולארי כאשר נחסמו לשימוש יישומים כמו סקייפ ו-Viber.

לאחר אישור הצעת החוק בקריאה ראשונה במליאת הכנסת, ציין שר התקשורת גלעד ארדן:

"בכוונתנו לשמור על כללי תחרות הוגנת, שימנעו מבעלי תשתיות התקשורת את האפשרות לפגוע ביכולתו של הלקוח לקבל שירותים באמצעות ספקים אחרים המתחרים מולם. צעד זה יגביר את התחרות בענף, יביא להוזלת מחירים, ויאפשר לשחקנים החדשים להציע מגוון תכנים רחב גם באמצעות רשת האינטרנט"
