Can someone explain lighting to me? Like i know a few basic things. But i feel like there's more out there to understand.

Short light is supposed to make the character look slimmer and adds more depth and Broad light makes a character look larger but also flattens the figure out.

Hard light is better for revealing tiny details while Soft lighting is better for making things look smoother and flattering.

I know that high atmospheric lighting can make something a chill/friendly look while low atmospheric lighting can make it look more serious/dramatic.

The color of the light affects the mood.

Generally speaking you want to have your lightsource be infront-above-left or right of your figure. which highlights their face/bust area.

I know that it's good to have only one main lightsource.
I know that if carefully placed, rim lighting can help your character pop off from the background.

I know that shadows/cast shadows purpose are to describe the form of an object or figure and can and should be adjusted or removed if they act against that.

What else is there? What other tidbits of information do you have swimming around in your mind when it comes to lighting?
