I do commissioned images using photoshop, digital painting and composite photos. This customer (in the USA) is saying that because he commissioned the work he owns the copyright. I've read up on the subject and he doesn't meet these conditions. I've completed what I feel is a beautiful painting which has taken me days to complete for £20 (yes I know!) and I want the option to print limited copies locally. He is saying I can't do this without his permission and he will take any profit and I will get nothing as he has paid me for all rights.
He hasn't got the image yet and he hasn't paid me. He used to work as a lawyer and is trying to bullshit me.
AIBU in telling him politely the copyright is mine as the artist and he can suck it up?
