My image: t-shirt used at ZDayZ 2008 http://asianguywithacamera.com/temp/zshirt01.JPG (car is mirrored) No permission requested to either myself or the owner of the Z (who hired me for the shoot). How far should I take this? The only downside to squeezing them for all they are worth is that I don't want to ruin the Z owner's reputation within the Z community. The last time one of my images was used without permission in an advertisement, it was easy to milk the cow since I could care less about the company that used it. This is a more touchy situation.
