Not very useful Only any use if you are using one of the films or papers hard-coded into the app. Needs an option to calculate exposure without reciprocity correction.
Excellent app I love how this app calculates exposure time factoring in reciprocity failure of various types of film, and even includes a countdown timer. Brilliant!
great and handy app for pinhole shooter and designer would be nice if measure shutter speed can be in 1/Xs as well as sec, one less math to do on the go. use light sensor to get EV is a nice touch tho!
EXCELLENT The best of all
Nice Good app...works well
