"hypothetical"  question:

Is it ethical to take a photograph of a person off the web, let's just say it's some everyday person, take the photograph into photoshop, make a few small changes to it, pass it through a filter or two, maybe even add a little hand painting to the photo (emphasis on little), and then pass it off as your original artwork with NO MENTION to the fact it was originally a photograph? In fact saying you painted it? Is this really ethical?

If you take the same circumstances as above except you make it a photograph of a famous person...is it even legal to do this?

I would appreciate people's input on this question
