Also, digital photography brings into question what is photography and what is digital art? When I can add elements that were not original in the scene, is that still photography? Or does that become art? If I retouch an portrait when does it crossover into artwork?

Photojournalists are held to the standard to take the scene as they arrived and saw it. Fashion photographers just make the model look great. But if they make the model look lots thinner are they causing esteem issues with the viewers? Can I take a picture of a kangaroo and cut-n-paste him into a scene with peguins and still call it wildlife photography? What are the boundaries?

Can I lighten/darken? Can I crop? When does Photoshop stop being a photo and become digital artwork?
