I remember once going through the AGO (Art Gallery of Ontario, Matisse exhibit) with a friend. She wanted to stop and study a lot of the images, I tended to take them in quickly and more on. Especially with the new rapid fire , digital image, photographer are used to evaluating quickly, and moving on quickly. A painting, where everything in the painting is created intentionally and which has no un-intentional elements can be more demanding. With a painting, you have to ask, "why did the painter put that object there and portray it in that way, what was his message?" With a photo, a lot of the photo , unless done in studio, can be un-intentional. You can study it as long as you want, button the end, it's still unintentional. In photography we look for elements that work together to portray a mood. We function on the basis of recognition, not creation. With a painter, it's "what did he create and why?" with a photographer, it's "what did he capture and why?"
In a lot of instances for a photographer the why is "because he/she was there." and there's no need to go beyond that.
