To be clear, I sometimes shoot events for free as a favor. And I sometimes shoot concerts or sporting events just because I feel like it. And if you find my photos on Flickr I'll probably give you permission to use them for free. (Though if you want to pay me, that's fine too and I do sometimes get annoyed with the presumption that I'm not going to ask for a fee.) But I'm probably not going to take you up on a minimum wage offer unless it were something I was going to do anyway.
