So I offered to PeridotCipher to make a guide for shading things, and as I was making it, I realized that A) it was going to need to be a lot longer than the 20 pictures allowed per wattpad story chapter, and B) I was having a lot of fun making it. So, now, I present to you the first of potentially many of A Mouse's Guide to Arting, a guide to basic shading.
Anyway. Best to start simple, with, say, a light source (yellow sun-like circle) and a box (the box).
Now it would seem really simple, shading this: the stuff closer to the light source is lighter, and the stuff that's farther is darker, right?
Well. Yeah. But with more complex things where you've got stuff in front of things and a mess of objects casting shadows, it can get complicated. So we'll just start with this to make sure we know what we're doing- you have to lean arithmetic before you can learn algebra!
(... Ugh. Math. I hate doing math. Why does that have to be such a good metaphor? I don't want to do math.)
Anyway!
So, it helps if you think of your light source as being able to see. So, uh.
Meet Mr. Happy Sunshine Light Source. He's, uh. A light source. And. For the sake of this guide, he'll be looking at this box.
In fact, let's draw an arrow, to show Mr. Sunshine looking at the box.
