Title: The render Looks real, but is it really real?
Post by: Alex Abarca on 2014-04-07, 20:17:21

Is there a method or way to validate the measurement of LUX or illuminance in corona? It will be nifty if the software can support ies photometric studies.

It can be done with some thought - the image units correspond to watts/m2/sr - so you can compute image, save it WITHOUT GAMMA and convert the units for yourself ;)

Sometimes this feature is really necessary and I even posted some sort of request for it some time ago https://forum.corona-renderer.com/index.php/topic,2308.0.html - just don't mind the corona ao part - that was quite lame of me :)

I really didn't understand the response I got...But if you don't mind looking here, Harvard University Graduate school of design publish a white paper on measurement-based day lighting with the help of Pierre Felix Brenton.
