I am looking for microstock photographs which have the look of _casual snapshots_ of people. Almost everything I've seen looks too heavily "produced", e.g. too well lit, people all look like models, etc. This is for use in a social psychology experiment. Does anyone have any ideas?  Do you know of any relevant microstock links? I would greatly appreciate it.

Thanks, I'm checking it out right now. You're right, this is non-commercial.
