Thanks for that link Ferny, it was a good read.
I've taken the occation street shot, and never had anyone mind. Although from what I've read on the net about Street photographers, many of them say that they only have a couple of problems. I think for the most part, you're good.
I do think that carrying around business cards, with your web site is important. During the NHL finals last year, I was on the Red Mile here in Calgary, on a couple occasions a photographer would come up and hand me card that said my picture might have been taken, with a web address.
I've always wanted to get more in to street photography. Doxx touched on this briefly and said it was legal to take photos in a public place. I understand that for commercial purposes, you need a model release, but what about for artistic? Lets say, if I want to put it in a book, sell it as art or post it on the internet?
