Description

Expositor is a handy slide-rule based exposure calculator for photography. Pick the scene you're shooting, then slide the roller until your camera's ISO is lined up beside it, and every combination of F-Stop and shutter speed on the right will get you close to a perfect exposure.

For a more creative example, let's calculate shooting sports on an overcast day with a shallow depth of field (F4) to isolate the subject, and a fast shutter speed (1/500s) to stop motion. Match the F-stop and speed, then check the ISO value next to 'Heavy overcast day' to see how sensitive your camera needs to be. In this case, it's ISO 200!

Use Expositor in the field if you don't have a light meter handy, or use it to train your brain to be its own exposure calculator. Expositor is here to help you shoot great pictures!

More instructions and detailed usage examples can be found at http://expositor.wunderkemmer.com/Instructions.html.

Customer Reviews

Relates lighting to the exposure triangle

Good tool if you want to tweek exposure for depth of field, fast movement, or lower noise. I shoot in Av most of the time, and this app helps me ballpark the ISO and Tv settings possible based on the expected lighting conditions.

Better than nothing...

I’m not depend on any value numbers I use to meter with my Canon camera but with this thing I might have some good starting point... than I fine tune it to get the perfect exposure… I will have good use for still landscape night shot.

Perfect app, totally love it

For those who use vintage film cameras, this app is a must
