Been done already surely?
Has anyone been in the Photo department in Boots or any supermarket recently as people stand trying to make shitty Smartphone pics into shitty paper photos? There were queues and queues of people over Christmas shoving their iPhones in and waiting (possibly for weeks) as the photo kiosk tried to work its way through thousands of terrible camera phone images that have never been backed up or downloaded?
These self-service kiosks are pretty much ubiquitous and instant to use. Between Kodak and Fuji I can't see anyone else getting much of a market hold. It's an area where brand name doesn't really count but convenience and cost do.
