It's been a longtime coming! Version 3 of the original, and the best, Reciprocity Timer app for film photographers includes:
- a completely re-vamped user interface
- a completely re-designed Note Taker that's easier to use - you can now drag and drop notes between categories
- support for sharing so you can Export, Save, Airdrop, Text, Email or Post Reciprocity Timer Custom Films, Notes and Camera Data. Export your stuff to iCloud, Dropbox wherever your phone has access to via the "Files" app. Import your data back into RT later.
- re-developed notification system to ensure you get notified when your long exposures are ending
- Redesigned Custom Film editor - can now calculate a reciprocity curve from as few as 5 or 6 data points. If you can get at least *some* information chances are RT can work with it to let you use that film.
- added new films including support for Rollei, Berrger, some IR films, CineStill 50D and others.
- added Film Holder support so you can use the note system to record even more details about your shots. RT will keep track of what holder you are using and the status of each frame. It'll warn you if you select the wrong film or if you try to shoot an unloaded or previously exposed holder.
- Updated Zone Editor. You can now export your Zone-Marked up note images as Jpegs (with Note Exif Data attached) to your photos or the cloud.
- many many bug fixes and improvements

Description of Reciprocity Timer
Manage your film photography from start to finish!
Initial purchase allows you to calculate reciprocity for all the films included by selecting an observed exposure time. This non-pro version is suitable for people who just need to calculate an exposure that includes reciprocity adjustments for their selected film. It will suit many users who don't require note keeping or a camera database etc. It's most suitable if you are new to film.
More advanced users will want to upgrade after their initial purchase to the pro version.
This will unlock all the additional features of the Note and Camera database as well as custom films and filters.
There is no need to upgrade if you just want to calculate and time reciprocity for a particular film and you always use the same camera.
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.
Once you upgrade then the one app does it all - notes, filters, exposure calculations, custom films, zone system editor, film holder management as well as the reciprocity math!
A comprehensive 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 NDs and Polarizers.
Keep detailed notes and share them. Share your adjusted exposure times with colleagues.
This app makes film photography a breeze.
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.
Watch companion app now included. To install the app use the Apple Watch App on your phone. Ensure your watch and phone are paired an unlocked and scroll down the list of available apps to Reciprocity Timer. Select Install. You can also turn on "Automatically Install Apps".
