It`s from http://www.lifehack.org/articles/lifest ... mages.html (also full article)

Guess it could use and update, I think it`s from 2010.

Nice find

- good infographic
- and realisation that f-stop, exposure and iso level apparently do the same exact thing in octane, make it bright or dark

- f-stop should be (just) aperture setting, exposure should affect motion blur (and the amount of light), ISO would obviously be samples - athough it is film sensitivity, or in digital SLRs the light sensor sensitivity - all difficult to translate to render settings since it involves more physical attributes - actually those things are relative to physical limitations of lenses and sensors, something that render engine doesn't really has to deal with

- it is pretty necessary to learn how to take good photos, frame them etc, in order to get good renders..
- render engine essentially simulates a camera lens, not our eyes, which have HDR and auto exposure adjustment

they were supposed to have changed that? maybe they haven't done it yet.
