I’ve belonged to a stock photography community for about two years. There’s a big controversy going on over there right now as photography submitters are going after vector illustrators that may have referenced their work. While I can understand getting irritable over an obvious copy of a distinctive shot, getting in a twist over the similarity between your picture of a car and the illustrator’s vector car is why I’m pulling out. I have visions of photographers making 30 cents a download scouring a Dave Mack comic for similar poses so they can SUE!!! I point out Mack because I caught him doing exactly that with a magazine photo in one of his panels years ago. Referencing a photo for a drawing is as old as taking a picture, and I’m surprised photo people are just discovering this. Some of the back and forth reminded me of this.
