Predilux lets you predict the exposure (key light) measured by a light meter, by choosing a light source and a distance. Or inversely measure the distance to the light source by specifying the exposure.

Predilux takes into account camera settings (FPS, ISO, Shutter), source settings (Focalization, Lens, Grid, etc.) and gels (Diffusion, CTO/CTB, CTS, +- Green, and dozen of effects).

All results have been experimentally verified with a light meter in rental shops. Predilux does not rely on constructor’s data.

Great App

Great App, well done and really easy to use. Maybe a little bit expensive for the range of lights options, but I’m sure this will get better.

Appalling lack of a proper fixture library…very few units
