App description

Android App Analysis and Review: Exposure Calculator, Developed by Quicosoft. Listed in Photography Category. Current Version Is 6.1.1, Updated On 19/04/2025 . According to users reviews on Google Play: Exposure Calculator. Achieved Over 693 thousand Installs. Exposure Calculator Currently Has 3 thousand Reviews, Average Rating 4.5 Stars

Given an exposure (Aperture, Shutter speed, ISO), allows calculating equivalent exposures - set 2 new parameters (a combination of Aperture, Shutter and ISO) and the 3rd parameter is automatically calculated.

It is also possible to add up to 3 ND filters of up to 30 stops each to the calculations, handy for those long exposure photographs to blur water and clouds.

The app also includes a timer for exposures of 4 seconds or longer.

Main features:
 • calculates Shutter, Aperture or ISO
 • aperture range from f1.0 to f360
 • shutter range from 480s to 1/16,000s
 • ISO range from ISO 0.4 to ISO 3.2M
 • ND filter up to 30 stops, in 1, 1/2 or 1/3 stop increments
 • up to 3 stacked ND filters
 • ND filter modes: stop, density, ND number
 • bulb mode (up to 24h)
 • reverse filter search mode
 • ND filter calibration mode
 • timer for exposures of 4s or longer with alarm
 • night mode with 4 overlay colors
 • optional compensation wheel to account for reciprocity failure
 • unlimited number of presets
 • free and ad free
 • privacy - the app does not collect any personal data

Note: in the Shutter settings section there is a switch tor camera type. This switch simply selects how a small set of shutter speeds around 1 second are displayed, choose the one your camera adheres to. Exposure calculations work for all camera makes, this switch is simply for display purposes.

What's New

• We noticed a few screws were loose (metaphorically speaking, these were bugs). We tightened them. With digital wrenches.
• Polished the chrome and updated the flux capacitor (okay, fine, we updated dependencies). Future-proofing, you know?
• The result? An app that's marginally more awesome. Hit update and feel the subtle difference!

Simple, functional, packed with useful features, no ads. Pretty much a must-have for calculating long exposures and such. The night mode is a life saver in the dead of night. As for suggestions, I wish there was an option to go beyond 1/32k, because there's cams like the a9iii that can do 1/80k of a second. If I could give more than five stars, I would have.

I almost have it figured out. I went to the linked YouTube vid and every comment complains that there is no sound/explanation of what you are seeing. Could you either add sound or add instructions in the notes area of the video. Thanks.

[Jan. 23 2020 Update] This is the best ND long exposure calculator that I have ever used. Simple, accurate, UI is layed out properly with attention to detail. Everything one could ever need for long exposure work. It is 100% free with no annoying ads that could disrupt the user during field work. I also greatly appreciate the developers time and effort for continuously updating this app that I have been using for years. Thank you for this! Well done.

Great app. I fly drones and when I manually set frame rates and shutter speeds to 30fps and 1/60, I have to use ND filters. Instead of guessing how many stops are necessary for that particular exposure, I can bring along a camera where I can determine correct shutter speeds based on the histogram. Now, I can convert shutter speed to ND stops. No more guessing. I don't have to bring back the drone just to change ND filters. I can get it right first time out.

I've been trying to find a way to calculate the right iso/asa to use indoors, with my brownie box camera. I even asked in a brownie camera subreddit, with no answer. This app helped me work out what film I need to use. I usually just go by the light meter of my dSLR, but that obviously isn't an option with analogue, so this app has helped me cut out a lot of time wasting, trying different films for the right result

It's probably my lack of understanding, but I can not figure out how to display shutter speeds in excess of 1/80 or 1/60 (depending on the mode, EV in particular). I am presented with the display of 1/1... or 1/2... or some similar representation of shutter speed, which means I have to go back to the highest represented speed (1/80 or 1/60) and calculate in 1/3 increments how far I am from that speed to know the speed which is being displayed. Your thoughts on this will be greatly appreciated.

This is an excellent app. It is very simple to use with no learning video needed. I am not sure that the app gets the exposure right first time, but the light was changing and my test shot was probably a little off. So it was probably me that was at fault. A very useful tool for anyone doing long exposure photography. Thanks!

Awesome tool. Once the Devs let me know that you can go into the settings and adjust max and min ranges this tool was exactly what I jad been looking for.
