though it is a little suspect that buddy just sends pics out, unmarked, unmentioned, and then once they get used he's all "dude pay me now. that's mine"
that's pretty much what those street vendors do over in europe. they jam a brochure or magazine into your hands and once you hold it they refuse to take it back and pester you for payment.
Yeah, that might be true, but you have to think of the relationship between the photog and the snowboarder. they were good friends, and I'm sure that was the reasoning behind it. I admit, I'm no professional, but I give my friends my shots of them all the time, and I know a handful of professionals that do the same with their pics. But when all of a sudden someone else is actually making a profit (no matter how indirectly) at your expense, of course you'd want payment.
