As has been mentioned, photographs are obviously 2-dimensional art. Still photography is a huge and varied market in today's world of news and beauty.
One type of photograph I like and even insist on in certain circumstances, is the photograph of the meal itself that accompanies the recipe in a cookbook! I don't know if it's that I'm dyslexic in this area, but the photograph adds so much to the whole idea of preparing the meal.
If I am looking for recipes of say, ways to cook chicken, I am already focused on a sound idea, and I may not need a photo, but if I am just browsing, seeking to be inspired, seeking to expand my cooking horizons, I need a photo. And these cooking photos are always a lovely close-up, suggestive, in mouth-watering color, with an interesting composition, good lines, nice background, etc......going right along with the artistic guidelines of a good photo....
And it makes one wonder who got to consume that luscious meal after it was photographed!
