Conánn had shown us a video relating to ‘light fall off’ in photography, he also exlained that this information can be taken into Maya when lighting there, and can also be taken into your art in general. I done a bit of research to follow up, although the videos I found were not as well informed as how Conánn had explained, they still gave a similar explanation.
The video below had to be shared, amazing reference on lighting the head from different angels. 🙂 love it.
I think this is similar to how Conánn explained light fall off, a table was shown in the video, this was the closest I could find. It explains a lot about how light continually decreases with increasing distance.
