i know there is an app that detects the amount of light (lux?) , but what im talking about this an app that allows you to select your chosen aperture size, and the app gives you the appropriate shutter speed according to the light condition. just like a light meter used for photography.

if i recall correctly, there is some of a similar nature on iphone, so it shouldnt be 'too' unachievable?

thanks for reading, anyone feels they need an app like this too?

and anyone willing develop such app? i believe it would be appreciated by many of the photographers here using mechanical cameras like myself.

thanks in advance.
