Hey CA, it's late and I release my thoughts.
Maybe some of you can help me to gain new perceptions or a better understanding.
When studying anatomy, I'm all fine with it. Because it has some guide lines which never change. Every man, woman or child is build in a same way - no matter if thin, chubby, muscular and so on.
But with light and shadow it seems different to me! Sure, there are cast shadows you can easily identify.
But that's it. There are so many possibilities, maybe MILLION ways of how light can bounce on a body.
And let's not talk about the colours!
Sometimes I wonder if I think too much about light and colours.
The human brain is no computer which can calculate lights and shadows like in a videogame.
But how do pro's do it?!
I don't know how to find out to shade stuff correctly. Muscles, arms and legs can be shaded like tubes if the light is regular and not strong but thats it...
I picked this artwork by Mike Azevedo as an example:
How does he know that the light falls THIS WAY on the Monster on the right side? How does he determines the colours of the reflection? Look at that grey on the back and the white on it's right side.
IDK how i could every find this out. when i copy photos with human models and learn a bit about values - it's only a minimal success because you all can agree that this monster has very little human shape. and also every light siutaion is different...
Sorry for the long text but its hard to explain.
TL;DR: How does an artist chooses the right lights and colours among the incredible amount of possibilities?
