Exposure Calculator is an iOS application for photographers to convert and calculate different exposure settings.
Exposure Calculator helps you to find the correct settings for your longtime exposures.
If your camera doesn't have a timer for longtime exposures, just use Exposure Calculator's built-in timer.
Shutter, Aperture, ISO:
No matter which parameters you want to use: Exposure Calculator calculates the remaining target value for you.
Exposure Calculator helps you to find the correct settings when using ND filters.
Built in timer for calculated exposure times greater than 2 seconds.
For very long exposure times, ExpoCalc can remind you with a push notification that the timer approaches the end.
You can configure Exposure Calculator to meet the capabilities of your camera. Choose which ND filters you own and let Exposure Calculator display only those to keep the list clear. Choose between multiple color themes, dark and light mode.
