Just read an interesting blog by Paul Melcher on Black Star Rising and thought I should share it as it raises some interesting points.
"Google has become a standard that everyone follows and copies. Most photo agencies these days emphasize the size of their archives and the speed of their search results rather than the quality of their content."
"Creativity is trumped by productivity. A photographer producing more has more chance of being sold than one who has great talent."
Although it's focused on the stock photography industry, I think there are a lot of parallels within commissioned photography too.
