Description

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 camera's 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 manufacturer's 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.

Questions & Answers

Q: What is an APK File?

A: Just like Windows (PC) systems use an .exe file for installing software, Android does the same. An APK file is the file format used for installing software on the Android operating system.

Q: If I install an APK from this website, will I be able to update the app from the Play Store?

A: Yes, absolutely. The Play Store installs APKs it downloads from Google's servers, and sideloading from a site like ApkClean.net goes through a very similar process, except you're the one performing the downloading and initiating the installation (sideloading).
As soon as the Play Store finds a version of the app newer than the one you've sideloaded, it will commence an update.

Q: Why ApkClean.net can guarantee APK 100% safe?

A: Whenever someone wants to download an APK file from ApkClean.net, we'll check the corresponding APK file on Google Play and allow user download it directly (of course, we'll cache it on our server). If the APK file does not exist on Google Play, we'll search it in our cache.

Q: What are Android App permissions?

A: Apps require access to certain systems within your device. When you install an application, you are notified of all of the permissions required to run that application.

Don't hesitate to contact us if you have any questions or concerns.

5 ★신세계네요. 지금까지 주먹구구식으로 대충 1~3스탑 올려서 찍었는데 이런 상반칙불궤 계산기가 있었다니.. 필름들 좀 더 많이 추가해주세요! 코닥 E100도 없어요.
5 ★Great app 👍
5 ★Quite probably the most simple, effective and clean app for reciprocity failure calculation. Definitely worth the money. I've had excellent experience with its accuracy for very long exposure times for various films, mostly Portra 160 and Fomapan. It would be very nice if in a future update the ability to add custom formulas for different films was added.
5 ★Great way to compare film exposure ratings. Would be awesome to include ektar. I've been going nuts with this tool now that I'm deep into 4x5.
5 ★Very useful for long exposure on film, especially with pinhole cameras. Calculations seem to be good, have to use different films to confirm.
5 ★Easy to use !!!
5 ★Fab for pinhole. I've always estimated my pinhole shots based on experience...which can be hit or miss. I've ended up with some shots -- that I would have way underestimated times for -- that turned out perfectly thanks to this app (20 minutes instead of my estimate of "about 5-ish..."). Thank you for creating this!
5 ★A fantastic app - thank you! Would be great if Lomography Colour Negative 800 was added if at all possible. Many thanks!
5 ★Good app but missing the data for Portra 800 Edit: updated review to 5 stars
5 ★I appreciate having this app at my disposal. Very helpful.
