So what if everybody in Iraq has a cell phone and an internet uplink? I have those things and... I shoot film. I would expect far better average image quality from an hp5+ throwaway or such. And phones and digitals do invite theft.
Using something like instax instant-print cameras might be a nice way to get people to take their shots, see the prints in real time, and write a few words on them. Could be like a massive instant print exchange.
One ethical concern I have is that people might risk life and limb to take their photos. Is it fair for me to pass that risk on to someone else?
