MIT researchers use ordinary cameras to create extraordinary interactive videos

03 Aug

Augmented reality is in the news plenty lately, but some researchers from MIT have put an interesting twist on the popular technology. Using new algorithms and as little as a few seconds of video created by a traditional camera, they’ve been able to create Interactive Dynamic Video, or IDV. The objects respond in a surprisingly realistic way as they’re poked, prodded and manipulated.

IDV records the tiny vibrations of an object in motion during a short video clip, and then uses that information to allow users to interact with the object virtually. The potential applications include things like monitoring the structural integrity of bridges or buildings. The technology could also provide filmmakers with a cheaper, less time-intensive alternative to 3D modeling. Case in point: this little green monster running around a playground.

See the video below to learn more about the research and its applications.

Feast your eyes on a Sony 24-70mm F2.8 G Master teardown

03 Aug

Teardowns are a handy way to satisfy the urge to see what’s inside expensive and prized electronics, while remaining a safe distance away and keeping warranties intact.

Behold, a teardown of the Sony 24-70mm F2.8 GM, a lens that sells for $ 2200. Sony’s own SGNL YouTube channel does the dirty work of prying it apart for us, giving us a close-up look at the inner workings of the fast full-frame zoom.

Samsung Galaxy Note 7 combines S7 camera with large display, S-Pen and iris scanner

03 Aug

In keeping with its established product innovation cycle, Korean manufacturer Samsung has today launched the latest model in its Note line of large format smartphones, the Galaxy Note 7. Judging by its specifications the new device looks like an impressive package but is in many ways more of a refinement of previous models rather than a radical overhaul.

The camera module, for example, comes with the same specification as the smaller Galaxy S7 and S7 edge devices. A 1/2.5″ 12MP sensor with 1.4-micron pixel size is combined with a fast F1.7 aperture, optical image stabilization and dual pixel on-sensor phase detection AF. The front camera has a 5MP sensor and F1.7 aperture.

Processing specifications are identical to the S7 as well. The US version of the device is powered by a Qualcomm Snapdragon 820 chipset while the international versions will come with Samsung’s own Exynos octa-core chip. All models come with 4GB of RAM and 64GB of internal storage that is expandable via a microSD-slot.

The Note 7’s characteristic 5.7″ dual-edge display offers Super AMOLED technology and a 2560 x 1440 Quad-HD resolution. It’s also the first display to feature Gorilla Glass 5 which should survive a drop from 1.6 meters height. As on the predecessor, the edges of the display are curved and offer Samsung’s unique Edge interface for quick access to contacts and apps. While some competitors have started to dispense with the headphone-jack the Samsung still offers this standard connector, next to a new USB Type-C port. All the components are powered by a 3,500mAh battery, which is a little smaller than the variant in the S7 Edge.

Notable new features include an iris scanner above the display that allows you to unlock the phone or access secured content. Samsung says that in the future the scanner will let you log into accounts or use Samsung Pay, but none of these functions are currently implemented. The design of the Note series’ characteristic S-Pen stylus has been slightly altered, too. It is now water-resistant and at 0.7mm comes with a thinner tip which should make for a more natural writing experience. 

Overall the Galaxy Note 7 looks like an appealing proposition for those users who like to work with larger screens and a stylus for photo editing. The camera module has already been tried and tested on the Galaxy S7 models and currently among the very best.

Lighting 102: Shape and Detail

03 Aug

"One light for shape, another for detail."

This simple concept, which I learned from photographer Jim Richardson about 25 years ago, forever changed the way that I thought about lighting. It's like a switch was turned on inside of my brain. Read more »

Lighting 102: Angle

03 Aug

The legibility from our fill light doesn't call attention to itself. It just makes your other light look that much better. It introduces a balance; a range; a relationship between the two lights.

Think of it like a backup band behind a soloist: the band is there to fill in the gaps, add background and make the soloist sound even better. Fill light is the music machine to your drunken karaoke key light.

So just like we did in Lighting 101, lets take a walk around the block and explore some lighting angles. For consistency, we are going to keep the same key light source for every photo on this page. So it is just about the lighting angles — i.e., no other variables.Read more »

Broken Ground: Poignant Earthquake Memorial at Epicenter in China

03 Aug

[ By WebUrbanist in Architecture & Public & Institutional. ]

disaster landscape

A visceral memorial to the nearly 100,000 victims of China’s 2008 earthquake, this weathered-steal monument and museum conjures images of cracked Earth left in the wake of a quake.

The Wenchuan Earthquake Memorial Museum was conceived of as an architectural landscape and situated in Wenchuan County, the epicenter of the earthquake in the Sichuan Province.

Green roofs look unassuming in the landscape while rusted steal provides a ground-hued contrast in the cracks winding their way through the ruptured site. The effect is powerful, giving visitors the sense that they are walking in the actual voids left by the disaster.

The quake was responsible for an estimated 70,000 deaths and left tens of thousands missing. The museum complex was created by the faculty of Tonji University at the request of the Chinese government.

The sheer magnitude of such an event is impossible to capture in physical form, but this design aims to at least give a sense of the devastation and places for remembrance and quiet contemplation.

High-profile camera expert leaves Microsoft, returns to Nokia

03 Aug

As the former Head of Imaging at Nokia, Juha Alakarhu was a key figure in the development of the Finnish company’s PureView cameras. The innovative technology was implemented in models such as the Nokia 808 or Lumia 1020, which by many mobile photographers are still viewed as the best smartphone cameras ever made. Unfortunately, slightly slower than usual camera processing speeds and the high cost of the technology meant the devices never really caught on in the mass-market.

When Nokia’s device division was sold to Microsoft, Alakarhu and his team moved as well, but now it looks as if Microsoft is pretty much abandoning its entire smartphone business, making redundant a large proportion of the employees that were hired as part of the Nokia acquisition. Camera expert Alakarhu is among a number of high-profile engineers who have already found a new role, though, and it’s with his former employer. He is returning to Nokia as the head of the Ozo VR camera.

If you’d like to refresh your knowledge on Nokia’s PureView technology you can read our interview with Juha that was conducted on the occasion of the Nokia 808 launch in 2012.

Instagram Stories launch as ‘disappearing’ photo and video slideshows

03 Aug

Instagram has taken inspiration from Snapchat and launched a new feature called Stories. With Instagram Stories, users can capture numerous videos and photos, alter them with stickers, drawing tools, and by adding text, then post them to a single ‘story’ slideshow that won’t clutter up followers’ feeds. Once 24 hours pass, these story posts will disappear.

Instagram Stories are only visible to followers when the account is set to private; likewise, users can block specific followers from seeing their stories. Though story posts do not allow comments, users can swipe up to see which followers and accounts have viewed the content. Instagram users can feature parts of their stories on their profiles, as well.  

Stories posted by the people you follow are accessible via a bar at the top of your content feed. The profile photo of users with new story content will be visible with a colored ring around it in this bar. Tapping on the profile photo will pull up the story and navigate the user back and forth within the story, while swiping will jump the user to a different story altogether.

Instagram says the feature will be rolling out to iOS and Android users across the globe over the next few weeks.

10 Photography Accessories You Can Buy at the Supermarket

03 Aug

Let’s face it, we photographers are always looking for new stuff to add to our bag of tricks.

As a studio photographer with almost 20 years experience, I have found myself repurposing a lot of stuff to use as photography tools in my photoshoots. I came to the conclusion that most of the stuff I have around the studio, or in my camera bag didn’t came from photography equipment stores, but rather from the supermarket, home improvement stores, or even one dollar stores.

Here is a small list of items that you can find easily in a store near you, which might help out a lot in your future photo projects:

1 – Cupcake nozzles

01

These nozzles are used by bakers to decorate cakes, and you can find them in many shapes and sizes. If you take them out of context, they make great light modifiers when used in front of a flashlight, allowing you to shape and control your light, when you want to do some light painting for example.

02

2 – Shower caps

03

This is something you can buy really cheap or even get for free in hotel rooms. I always have some laying around in my camera bag, and I use the white ones as light diffusers for flash or LED lights.

04

I also use the transparent ones as a rain cover for the camera body. It’s not something for heavy rainfall, but it can save your equipment in an emergency situation, and you can still see the LCD and camera buttons with it.

05

3 – LED light strips

06

These lights can be carried anywhere as they work with 3 AA batteries, and can be used in lots of different situations. I used them a lot as macro ring lights with the strip wrapped around my lens shade.

07

These lights are also great to create light bokeh backgrounds, just put them over a black surface and turn your lens out of focus.

08

4 – Multi-Purpose Opener

This tool is made to be used around the kitchen, but I have been using it for years in my studio for a lot of different purposes.

09

The main use I have for it is for that really frustrating task of trying to unscrew a stuck filter on the front of your lens. Even though there are specific clip plastic tools for that job that you can buy in photography stores, I always find myself breaking them or scratching some really expensive filter.

This multi-purpose opener has a rubberized inside and offers a much better grip, besides fitting every filter size you might have.

10

It is also able to open any metal or screw cap bottle if you happen to get thirsty, and, last but not least, it is a great tool to open stuck thumb screws like the one you find on tripods or light stands for example.

11

5 – Glow Stir Sticks

12

These glow sticks, besides being a must at any cocktail party, are also really fun to use as a light source for light painting. They can be found in different colors and sizes and can glow for a few hours, allowing you to make fun images like this next one.

13

6 – Shower Curtains

14

Shower curtains are usually made out of plastic or waterproofed fabric. They are really cheap and can be used as great accessories for light control.

I use white ones a lot as light diffusers, black ones as flags, and grey ones as backgrounds, but there is a lot that can be done with colorful ones for backgrounds or light color effects.

15

7 – Ball Bungee Ties

16

It’s amazing what some elastic cord and a plastic ball can do together. This simple, but really effective tool, is used most of the time to tie cables, but there are a lot more uses for it. I use them a lot to hold my flash triggers to the light stand.

17

8 – Spring Clamps

18

I lost count of how many of these I bought through the years. Every time I see them on sale anywhere, I just buy a few more.

These are a must have item in any photography studio, whether it is to make your model’s clothes fit a little better, to hold cables and power cords in place so I don’t trip on them, or simply to hold that reflector in that position that will provide the best reflection possible.

19

9 – Express Grill Pan

20

These pans made out aluminum foil are great if you want to make a barbecue in a rush. But they’re also great to use as gobos that you can use in front of your light source to create special light effects.

21

10 – Reusable Putty-Like Adhesive

22

This type of adhesive is a lifesaver for product and macro photographers that need to keep small objects in a specific position.

It is moldable, reusable, and doesn’t leave any residue when you remove it. I use it a lot in jewelry photography to keep things in place, and just remove it (clone it out) in post-production afterwards.

23

So, keep these tips in mind next time you are dragging your shopping cart down the supermarket aisles. Maybe you can find some great accessories for your photography!

googletag.cmd.push(function() {
mobile_slots.push( googletag.defineSlot( “/1005424/_dPSv4_mob-all-article-bottom_(300×250)”, [300, 250], “pb-ad-78158” ).addService( googletag.pubads() ) ); } );
