Nice work. I let people save the screen resolution images if they want. I don't think anyone is going to sell my screen resolution images commercially, and I don't see selling it myself, so I'd rather people enjoy it than keep it locked away. It may be precious to someone besides me, but they can't print it, and if it ends up used on the web then the thief is obviously not professional, and is not making money from it. It just becomes anonymous pubic recognition of my work. Yours is very nice work indeed. Let it replicate throughout the web. It is your immortality, not your fortune. Fortune level photographers are more rare than rock stars. Just some food for thought.
