A simple and effective film reciprocity calculator for photographers. Select a film type and metered exposure time - the calculator will provide a reciprocity compensated exposure time. The app includes an exposure timer so you can time your long exposures. You can also use a slider to adjust exposure when you have filters attached.
The app supports a wide range of film stocks and allows the user to add various common exposure filters such as ND and Polarizers.
The app includes in-app purchase to unlock pro features including a note-keeping feature, the ability to add custom films and the ability to select often used film stock as favorites.
You may need to setup Reciprocity Timer in Settings -> Notification Center to ensure the app's timer can notify you when exposures are ending and your device is asleep.
This is a maintenance release to support iPhone 7 and 8.
Bug and crash fixes. Added iOS 11 Support.
Changed timer so exposures under 2 seconds can now be recorded.
Fixed export to Dropbox.
Changed night-mode to red.
Ratings and Reviews
Not sure why this app doesn’t have more good reviews. Best app ever for anybody using film.
Great app for film photography
Before this app came out I used to refer to the manufactures instructions for each kind of film used and they do not have the additional information like filter compensation etc. I find this app extremely useful and have everything calculated for you including long exposures using film. What I also love about this app is the auto note and the feature to take pictures as attachments and the zones editor is a great feature recording what your thoughts were at that time do not have to remember everything thanks for the app made my photography easy.
Reciprocity failure - another request!
Hi Guys - another request!
I was using the app with PAN-F in the Hasselblad a few days ago, down the coast, to get some nice seascapes, and the exposure time ran to about eight minutes with the 10-stop ND filter. Can you set the app to suspend the iPod auto-lock function to keep the screen and the sound alive while the timer is ticking? That would be a real help.
Other than that, I'm really enjoying the app and putting it to good use to help me get some great photos (when I manage to do my part right!). The reciprocity times for HP5 and PAN-F seem to be pretty close to spot-on.
Thanks again - cheers! Chris.
