Exposure Calculator – Handy for those long exposure photographs

[App] Exposure Calculator

Exposure Calculator  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:

shutter range from 480s to 1/16,000s
ISO range from ISO 0.4 to ISO 3.2M

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 data and does not have Internet access

Permissions:
control vibrator: to vibrate after the timer expires
read external storage: to enable selecting a custom ringtone stored on the SD card to be played when the timer expires

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.

Exposure Calculator user reviews :

It does its job well and simply. The only thing I’d ask for is an option in settings to type in values for aperture and ISO – some cameras have odd apertures like 1.5. Apart from that it’s everything I could ask for.

Awesome for calculating new settings. What I’m really missing, is the exposure value from any given configuration. (Like the one from toolstud.io) Update: Awesome update, exactly what I was hoping for!

  • Hey there, thanks for your comment. The app calculates the EV internally to determine the new exposure, I can look into surfacing this value as part of the calculation. Update: this will be available in version 5.4.0.
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!

  • Thanks for taking the time to leave a review, I’m glad you enjoy the app!
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.

  • Thank you for taking the time to review the app. I’ll continue updating the app regularly to keep it fresh and relevant. Have a great one!
downloaded this app just to say i loved reading the developer’s comments. i ordered my first drone this morning and a set of filters. can’t comment on the app yet, but I’ll update once i use it. for now, 5 stars to help offset the “i don’t know how to use this and instead of trying to learn I’m going to rate 1 star” foolishness

  • Thank you! I’m glad I can provide some amusement while replying to the reviews, all in a day’s work! Let me know if you have any questions about the app, I can be reached via the “Feedback” option in “About”.

Used this for some night time shooting and the settings worked as hoped. Please remember you have to know how to set your test shot first if you want to get correct results. So this may not be the app for you if have not mastered that yet, but if you have then get it.

Great FREE app. Note the word ‘free’ for anyone critical of this app. Makes life much easier when doing long exposures. I for one fully appreciate the time the developer has put in to this. Recommended.
