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.

gets you close
I am doing long exposure photography where I add a ton of ND filters, and need to calculate the new exposure time. This gets me close but there are a number of shortcomings: no partial f-stops like f9, no limited shutter speeds, and it would be nice if it had an ability to add x% to the total exposure time to compensate for ND over 10 stops. In an app market where the competition is terrible to non-existent, it's about as good as you're going to get, which is about a 3 star app
Perfect for what I was looking for
This app is perfect for large format cameras. Take a reading using a light meter, or even a digital camera. See what the exposure is that you get, input it into the app and then adjust your aperture to get the new shutter speed you’ll be shooting at. Easy and very customizable.
Excellent for calculating ND filters exposures
Comprehensive app for calculating exposure times, especially when wanting to dial in different variables such as neutral density filters vs. shutter speed vs. ISO vs. aperture.
Thanks to the developer!
With Family Sharing set up, up to six family members can use this app.
