Sean McHugh continues his series of tutorials with a detailed article on dynamic range.In this tutorial he explains how the dynamic range is measured and how it is correlated with bit depth. It worth to note that he stresses that the correlation between these two (bit depth and dynamic range) is not that simple... Read more to find out why.

First I've seen this article in the American Photo Magazine, and now I found it in the Internet, so I can share it with you. It's good when people give some credit to work of the wedding photographer and appreciate his/her work:

...It's only recently that they've been widely recognized for their multifaceted talent. In the course of a wedding day they serve as architectural photographer, documenting locations; as portrait photographer, flattering the day's key players; as product photographer, shooting a closeup of the rings; and as photojournalist, telling a story, under pressure, with pictures...

Even in the famous series of "Friends" the phrase that "camera adds 10 pounds" was used. And it is taken as a matter of fact. But do you know why it is so? Do you want to find out? Then read the article "Smile and Say 'Fat!'"

Chuck Westfall, Canon’s director of media and consumer relations, discusses the EOS 1D Mark III with DigitalCameraInfo.com.

DCI: Other than the dual processors, how are you able to increase the camera’s processing potential and reduce noise?
Westfall: Besides the 14-bit and the improvements of the Digic III, which is really considerable in helping to reduce noise, other things we were doing had to do with the actual sensor itself as opposed to just helping the processing side. Number one, the fill factor or the percentage of each pixel is actually occupied by a light-sensitive portion that became bigger. The micro lenses were improved. As a result of those two things, the signal-to-noise ratio which affects noise was improved as well. With better signal-to-noise ratio coming in, we were able to have a cleaner signal to start from. The Digic III helped us clean up noise that may have been left over.

The 1DS entered in the professional segments where we've never been, in the studio. Canon has always been strong in sport, but now we are embracing all the ranges - fashion, reportage, and studio.

Yesterday Canon has announced their new improved 1D Mark III. In many ways it's a completely new camera. There are so many new features and niceties that it's hard to grasp at once. And now we have even more details about this great Camera - read the Canon 1D Mark III White Paper (PDF 3.34Mb - 63 pages) at RobGalbraith.com.

The EOS-1D Mark III is the ultimate instrument for high pressure, high-speed photography, and it can do much, much more. It has the image quality, the ease of control, the speed and the flexibility to adapt brilliantly to just about any condition. Features such as the new integrated cleaning system make it easier to live with. With Live View, the possibilities are limited only by the imagination. The Dual DIGIC III Image Processors give it dazzling speed and the 14-bit output will help to make superb prints and magnificent magazine spreads. The battery data is a source of reassurance. Additions such as safety shift, highlight tone priority and high ISO noise reduction make stress-free success a given.
