Realizing that viewers/readers are enamored with large photographs, two national newspapers have recently featured large photographs of current events. The size of these photographs are in the range of 1000 x 650 pixels (which is the favored size for displaying my own images on my web galleries, and certainly for my multimedia slideshows). The response to the Boston Globe's The Big Picture is phenomenal, and if you haven't visited it yet, you should.
Interestingly, the staid Wall Street Journal has followed suit with its equally attractive Photo Journal which features a photo essay on Katrina stories by photographer Joseph Rodriguez.
For anyone interested in photojournalism, these two websites ought to be bookmarked. The Big Picture's photographs from the Olympics are just extraordinary.
