This is one thing that I haven’t thought of much. One photographer I know did this shot… http://www.lemarchestudios.com/gallery/Fashion/ody_port_2.jpg When I received my SU-800, I thought it would be neat to replicate this shot that I otherwise wouldn’t be able to do with the stock flash since it always emits some light… http://images48.fotki.com/v1407/photos/1/101317/2816904/HLGunBW-vi.jpg I’m friends with the subject in the original shot, so I sent him my version. After some comments and critique of both images and comparing them he suggested that I never release/sell the shot or make it public since he believed it might be copyright infringement. Now my initial thinking is that there’s no infringement going on here. Perhaps if it was the same model or brand name. So my question is, would this photo somehow be some form of infringement? And as a follow up, what about other photo’s? Some photographer snaps an image of let’s say a tree in a park and sells it. Then let’s say I like the shot and am able to almost replicate it on my own seeking out similar lighting conditions, I too snap a pic and want to sell it of the same tree in the park. Would that be violating any copyright laws?
