Photo Exposure Calculator

Photo Exposure Calculator


This software was created to help you to configure the approximate value for the Light Value (LV), Exposure Value (EV), shutter speed, ISO and aperture.

In photography, exposure value (EV) denotes all combinations of a camera's shutter speed and relative aperture that give the same exposure.


How to use it
With your touch or keypad down/up, you move de ruler.
Establish the brightness (EV) of your subject, using either your hand-held light meter or the descriptions on the calculator. (Note that the descriptions are only a guideline - if you're working from them you may wish to bracket your exposures.)
Slide the sliding scale so that the ISO value of your film lines up with the appropriate EV value. Then you can read off aperture/shutter speed combinations from the lower pair of scales.
This version of the calculator is reversible. Use the side with EVs 8-16 for bright conditions, and the 3-11 side for dim light.

Simple calculator but I'm unable to read the shutter speed. It's cut off by the ISO/Aperture slider.

Something is missing Good simple idea, but implementation is lousy

Okay Seems to function well, but this is a reflected light meter, not an incident meter. Incident meters read the light actually falling on the subject using a white inverccone, and are used differently. A reflected light meter reads the light being reflected back off the subject: this is why white objects and black objects often look grey instead of their correct shades because the exposure needs adjustment. And before anyone criticises my comment, I have over 30 years experience as a professional photographer.
