Pictures of President Obama
The New York Daily News has published a series of photographs by the official White House photographer Pete Souza which are excellent.
Most of these pictures are fun to look at. It goes without saying that they are all really good technically.

Pete Souza is a fantastic photographer, and he uses great equipment. Normally he shoots with a digital SLR which uses a full frame 21.1-megapixel CMOS sensor which is roughly the same size as a 35 mm film negative. His choice of cameras is the Canon EOS 5D Mark II.
This $2,700- Canon camera is thought of by most people as a much better value than the full frame $7,999- Nikon D3X camera. Many reviewers think that the 24.5-megapixel Nikon D3X is indeed a somewhat better camera, but not nearly enough better to justify the enormous price differential that Nikon is trying to get. In fact many long time Nikon users are boycotting this camera because of what they see as price gouging.
This particular picture of the Boeing 747 Air Force One caught my attention because there has been so much attention recently paid to pitot tubes, after the in flight breakup of the fly-by-wire Airbus flight 447 Air France airliner over the middle of the Atlantic Ocean. These pitot tubes allow an airplane to accurately monitor its air speed.
In Paris at the Gare Nord train station I found it fascinating that the Thalys high speed 300 km/hr train which I had just arrived on from Germany also uses pitot tubes. I have ridden on this train many times, and once I finally got my Garmin GPS to capture enough satellites to measure the speed. It indicated an exact speed of 186 mpg which equals 300 kilometers per hour. Please forgive the terrible quality of this photo...I took it using an old cellphone under low light conditions.
