There is a new movement going on now... mobile phone photography - and it's bringing surprising results. I love Misho Baranovic's work which is part of the EYE'EM awards.
EYE'EM is an international team of creative, designers, and developers located in Berlin who love the details in life and capturing them on your cell phone to share with everyone else.
Also check out Pixels At An Exhibition held at Rae Douglas’s Giorgi Gallery in Berkeley with amazing pictures, all done on iPhones. No editing on a computer was allowed, and suspect images were checked and removed if found to have been edited elsewhere. Just those amazing real life moments caught on a camera.
