First Accurate Digital Map Of World’s Rivers

Mon July 26, 2010

Bernhard Lehner, an assistant professor in the geography department at McGill University, Canada, has designed a detailed digital map of the world’s rivers after seven years and thousands of computer hours work. The global map detailing the world’s rivers has been posted online courtesy of National Geographic under the title, “The World’s Fresh Water.”

Though there are maps of individual country’s rivers, there was nono that was seamless and covered the world where the rivers flow from one country to another. So in 2003 Lehner set out to build it.

Electro Wetting (EW) Display

Electro Wetting (EW) Display

Dr. Han You and Professor Andrew Steckl of the Nanoelectronics Laboratory at the University of Cincinnati have experimentally demonstrated a new electronic display that contains colored oil droplets stacked on top of each other. The three layers of oil dyed red, green, and blue are separated by two intervening layers of water, and sandwiched between electrodes. Divide these layers of colored oil into aligned rows and you have separate pixels capable of displaying colors.

When a low voltage is applied to the water layer next to one of the colored oil layers, the oil moves to one side and is replaced by water [electrowetting (EW) technique], allowing the colored oil below to become visible. A white background is created by applying a voltage to all three layers of the stack.

These EW reflective displays have extreme thinness, low power consumption, and wide viewing angle. Combined with its high resolution, the EW vertical stack structure offers the potential for a variety of future e-paper and flat panel applications, such as touch commands and animation.

The Challenges Of Still/Video Convergence

Sat July 24, 2010

Now that video seems to be ensconed as a valuable addendum to still photography — and photographers turned videographers have touted the anyone-can-shoot-video hype of how wonderful and easy it all is, regaling us with realms and realms of video footage shot with HD DSLRs — clients now increasingly clamor for video production from photographers.

Stephanie Rausser specializes in commercial shoots involving lifestyle and kids, and finds just that: about every other client who now calls her with an assignment to shoot stills ends up inquiring about video production, too. In an interview with PDN, she says, “It’s way more complicated than people perceive it to be.

Public Photography Increases Security

Fri July 23, 2010

Photographers have been — and are still being — hassled by security personnel and police over photographing in public places, especially if said places are deemed high security. However, we have also witnessed police appealing to the public — and even going to Flickr — for photos about events where they want to identify perpetrators of crime. The recent G20 Summit in Toronto comes to mind where Police used public photos to identify members of the Black Bloc.

Model Crystal Renn Shocked At Being Digitally Retouched

Fri July 23, 2010

Model Crystal Renn, a Plus-size model and poster woman for curvy girls everywhere, is in high demand, has been published in Vogue and Glamour, walks the runway for Jean Paul Gaultier, and is the face and body of Dolce & Gabbana ads. But as a teen, she fought bulimia and anorexia.

So she saw shocked when she saw the published results of a recent photo shoot she did for charity Fashion for Passion. “I didn’t think it was an accurate portrayal of my body in any way. I’m a size 10, and that’s more like a size 2.

Photographer (and wouldn’t you believe it’s a photographer the culprit) Nicholas Routzen defends his action: “The minimal retouching that I did do, it’s nothing you wouldn’t see in any magazine today.

What to Look For in a Photographer: A Model’s Perspective

Thu July 22, 2010

As a photographer, you may know what to look for in a model. But are you the type of photographer that experienced models want to work for? Aimee J. Martin started modeling at the tender age of 11 and shares her rules of thumb how she choose who to model for: “When I found the best, I stuck with the best. I had suffered through complete failure shoots, and complete extraordinary and prodigious shoots.” And I like the bit of advice she leaves models with at the end.

Read Don Giannatti’s rebuttal who seems to be telling models to put up and deal with the famous photographers who hit on them. We disagree. The world-is-a-changing and intolerable behavior from a photographer, artist, movie star, even president is not to be put up with anymore.

Stanford Releases Open-Source Camera Software

Thu July 22, 2010

Computational photography refers to the ways computers can extend the capabilities of digital imaging by combining multiple photographs taken with different camera settings to create an image that could not be taken in a single shot, or with an ordinary camera.

We’ve seen this capability already in some digital cameras, especially dealing with HDR (High Dynamic Range) where the camera shoots 3 or more pictures at different exposure settings, optimizing each exposure to capture and retain detail in the mid, low and high tones, then combining them in-camera to produce a single picture with detail all across the image.
