About 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 1 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:
* aperture range from f1.0 to f360
* shutter range from 30s to 1/8000s
* ISO range from ISO 25 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
* timer for exposures of 4s or longer with alarm
* night mode (Lollipop and above)
* optional compensation wheel to account for reciprocity failure

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.

Note2: if you're reading this the app will use English on your device. If this is not acceptable to you, please do not install the app.

The best ND calculator I have ever used. Simple, accurate, and has all the right features for calculating exposure with a neutral density filter. Keep up the good work.

Does one job well.

W70%
by W####:

I've tried other apps, and this one has the best set of features, and is accurate. Of course you should always test your ND filters for their exact f-stop number, because they may be slightly different from the manufacturer's claim, and so slight differences in exposure settings are not the fault of the app.

Q70%
by Q####:

It is really useful when the light is tricky and you have had to change your f stop or shutter speed and you don't have (or don't trust) your light meter. Limited times that it is needed, but in those times it has great usefulness. Well supported by the developer.

Fantastic app. I'm do a good deal of long exposure shooting and this app is a brilliant way to save doing math at -6C. I just love the night feature.

by Q####:

Just what I needed Perfect for timing bulb exposures for equivalent exposure for different time intervals. The countdown timer with alarm lets you easily know when to end the bulb exposure. I'm using it to record airplane flight trails at night and the camera requires any exposure over 30 seconds to be self-timed .

Love this app as an exposure calculator. It's simple and has everything you need to be able to adjust to get the perfect effect you want, unlike some other apps. Some of the other reviews I read who were expecting other things, obviously don't really understand what an exposure calculator needs to do

Q70%
by Q####:

A great app, with a small issue: the exposure should be corelated with the geographical position and current time. For example, a 300" new exposure at the dusk will be underexposed as the enviroment gets darker by the minute. Same for morning, when you get overexposed photos.

Excellent small little app.

Q70%
by Q####:

It doesn't change once you start it up. I was hoping it was reading live but it isn't after you start it up. so you have to position the phone where you want to read from, THEN start it up and it is locked. it will not change to a new reading unless you restart it....why not update it with a 'refresh' type of button???

Very useful for manual photography to find out different exposure combinations based on one correct exposure reading.
