I use this app all the time to calculate the bellows extension factor of my large format camera. It is super easy to use! I often do long exposures so the reciprocity tool is equally as useful. I just wish I could edit them or add custom films - some film stocks reciprocity times seem different than the film’s data sheet (but still close - like Ilford Ortho).
I stumble upon this app after seeing a video on YouTube about the Bellows extension. I shoot Hasselbald V 6x6, Hasselblad Xpan, Rolleiflex TLR, 6x9 on my Large Format, 4x5, 8x10 and the calculations are Dead On. Makes adjusting for reciprocity Failure a very simple task. Same for Bellows Extension on any of my cameras and it has and easy lens conversion from all the popular formats back to the 35mm angle of View. On top of that they have a Developer measurement calculator for the darkroom. It’s really simple and well thought. A must have if you are serious about film photography or just starting into this realm. It’s a joy to use.
