Curious if you street shooters have any guidance on the etiquette of taking street or environmental portraits of carnival workers, specifically in the midway? I ask because I'm good enough with people to try and get to know them if I feel like they're not threatened. But a midway is a different beast entirely since they're always trying to hock something. Am I obligated to play an expensive game for which I'll most certainly loose? If I stop and take a shot of street musicians I try and throw some money in. Is this the same situation, though? Maybe give them my business card and tell them I can send them a portrait if they'll send me their (semi) permanent mailing address? I want to set a goal this year to make an environmental portrait of as many midway workers as I can but I don't want to spend over $100 easy for something I'll likely never recoup anything on. This will also be a great test of the GX7's low-light/high ISO and autofocus capabilities. I'll really get to stretch them out.
