This application approximates the length of exposure for various B&W films (and some color films) in low light situations. In low light, extra exposure is needed due to reciprocity failure (also known as the Schwarzschild effect). As such, your cameras meter is not accurate in low light. This application approximates the proper exposure time (based upon manufacturers datasheets). A timer is now included in the application.The application warns when the user enters an exposure longer than described in manufacturers datasheets. Although the exposure in these instances is crudely approximated by mathematical extrapolation, it is crucial that users conduct their own exposure tests in these very long exposure situations.

An amazing app for large format shooters who want to accurately calculate shutter speeds due to reciprocity failure. This is the only Android app I was able to find that specializes in these calculations. The developer is also open to suggestions and even added a couple of film types per my request.

What a simply top app. Didn't think I'd be able to find an app like this, and there it is. Easy to use. Simple with no unnecessary frills.

Great way to compare film exposure ratings. Would be awesome to include ektar.

This will help immensly calculating long exposure guesswork.

Saves a lot of faffing doubly so now the time is presented in minutes on long exposures. New timer should prove very useful to save swapping between apps in the field.

Great app and even greater support from Matt. I recommend it highly. Saves much time in estimating exposure time from film manufacturers data sheet.

This is a great tool for us film shooters. Finally I can get rid of my manual sheets!
