I've had an idea for a sponsored event to raise money for charity (the charity I have in mind is Amnesty International). I (and other photographers/enthusiasts/whatever who wanted to take part) would commit to take portrait photos of a certain number of people in a certain month. (How many? Maybe 100, or 250 or 500 depending on the individual's commitment.). Probably the only way to rack up that quantity of photos is to go out on the streets, find an area with a nice backdrop and good lighting, and explain what I'm doing to passers-by and hope they'll pose to be portrait subjects. It's probably not going to be, and shouldn't be, easy getting that many portraits done in a month. Friends, family and whoever else I could grab would be asked to sponsor me per individual I take a portrait of (possibly up to the agreed target limit). Even 2 cents a portrait would add up with enough portraits and sponsors would raise a good amount. While they should definitely be portraits and not snapshots, I obviously wouldn't expect the pictures to all have the same quality as shoots where you spend an hour or two on one model. I still want them all to look as good as the constraints of time etc. will allow though. Any feedback on this idea? Presumably to post the images afterwards online, I'd need to get every subject to sign some sort of consent? Anyone else interested in taking part?
