There were a lot of topics and questions all over the Internet about joining Canon Professional Services (CPS). At Photo.Net I found this topic, which discusses this issue and answers on many related questions. So far it is the best source for this kind of information I found.

There is an interesting invention/discovery, though expensive for the market. The idea of the invention is to capture information about the direction of light so the photographer could refocus the image aftewards. But why should I explain it to you? Just read this article - Say Sayonara to Blurry Pics

This morning I steped by a bookstore. I picked up Lenswork and started leafing through the pages (starting at the end of the magazine). And almost immediately was captured by the photographs. The photographs were about animals in Africa. But it were not simple wildlife pictures, no. They are portraits that capture the spirit and emotions. I should mention that the photographs are white and black, which even stronger pull you in. Are you intrigued, want to see those photographs? Well, just visit the website of Nick Brandt, the author of those portraits.

While wandering through forum topics I've found a couple of articles that tell about how to Calibrate Adobe Camera Raw 3.x. The other article (Out of Gamut: Calibrating Camera Raw in Photoshop CS) is what the first one was based on.

If you need to calculate DOF, Parallax or Field of View for your photography needs, you may consider the page "Photography Calculators". Unfortunatelly it hard to take it with you in the field, when you need it most.
