I thought this might be interesting to film users. It's a Kickstarter campaign to fund the development of a smartphone app (iOS and Android) that allows you to quickly capture a negative to a positive image with your smartphone. I figure it would be good for previsualization and review before you get into your full scanning or darkroom print workflow.

I opted in early so that I can be part of the beta testing.
