That is always a tricky area that of copying anothers work; and I suspects its just as much a problem for other artists as well. I mean one could say that one image of a bluetit, taken at 500mm with a perfectly blurred background could be copying anothers rendition of the same bird in a similar framing and composition.
Where does the line between emulation of a skill/method (in camera or in editing or both) and copying divide the two? Essentailly all of photography is emulation/copying/derivative partly by the limits of the tools and physics itself - manipulation and composition of those elements allows for diversity and ones own style to emerge and editing also greatly enhances this process. So in a sense all your work is already copied from a or a number of sources.
Does this line become more blurred when money comes into play - I would say yes (purist artists would try to disagree, but money is a factor). With that in mind how much can we copy/emulate of anothers work before we are "cheating" them? Should selective colouring not be allowed based on the fact that its a direct copy/reuse of a process by another photograher (someone probably started it at some point)?
Ps I totally know what you mean I'm just being the devil in this
