I had original developed this iPhone app for personal use. I designed it to fit my needs. You can find out here why I felt I needed it. Since then, after having conversations with a few people, it seems others might be interested in using the app as well.
I have decided to release it officially. But before the general public get to see it I would like to do a beta test with a limited number of people. I have only tested it on an iPhone 7 to give me a preview of 35mm and 6×6 medium format film so far. If you have a different iPhone model or are working in a different film format and are interested in testing the app you can use the form below to add yourself the beta test program. Even if you have the same setup as me I would be interested in your views on the app.
Latest: I now have enough people for the beta test release. If you want to try out Viewfinder Preview you will now have to wait until the proper release, sorry.
