What's your point of view on copyright laws and appropriation for your own artwork? I know I do enjoy painting an occasional master copy, and find it very valuable to developing my own skills. I am not talking about something that crosses both a legal and ethical line like plagiarism.
I happened to find this thought provoking TEDtalk… on this very topic that presents an argument in favor of imitation.
Here's another interesting article discussing copyright protection of an entire culture!
I have feelings in favor of both sides even with my own artwork and images. I know whenever I did a project for a corporate client in graphic design, it was a given that they owned the results, and I always felt okay with that arrangement. I often see my design work on the side of trucks and billboards even to this day (from some 12+ years ago) and have to admit I feel a little bit of pride in a good way that they are still using those images.
However, I tend to feel a different emotion when I do my fine art images… maybe it's because it is more personal, but I would still see it as a compliment if someone likes it enough to copy it.
