Tutorial Value by WillWorks Tutorial Value by WillWorks
I doing this style again until I get some better understanding of AS3. Then I will make a very dynamic turorial. Also I am going back to the brown paper.

Value: The Degree of lightness or darkness of a surface. High value is light and low value is dark making highlight the highest value and darkest shadows the lowest value.

Light: The high value that illustrate the more exposure to a light ray.

Shadow: The low value that illustrate the least exposure to a light ray.

Shading: The low value on the object that illustrate the least exposure to a light ray.

Highlight: The surface with the highest value in an object.

Core shadow: The darkest surface in the shading. It is between the light and the Reflected light.

Cast Shadow: A region on a surface that has low value do to another object blocking the light ray.

Reflected Light: A reflection of light from one surface to another. An indirect light source.

I've mostly heard 'core shadow' referred to as 'form shadow'
WillWorks Feb 18, 2013   General Artist
That is interesting. I usually found it to be called the core shadow. Where did you recall it being called form shadow? I think form shadow is another way of saying shading.

a book by the painter Lee Hammon, the part about practicing painting a sphere...and in many books on drawing with pencil. Anything on the opposite side of the light course is a form shadow--or core if you want to use that term. Cast shadow I think is pretty universal.

One book I got The Art Of Perspective from Phil Metzger called the area shading that some other diagrams call form shadow. The core shadow is the darkest shadow following the crevice shadow (the crevice shadow is the darkness between to surfaces). It is the darkest spot between the lighter shadow near the light and the reflected light. All core shadows are shading (or form shadow) but not all of the shading/(form shadow) are the core shadow.

A painter in a book said cast shadow was always the darkest, amazing to me since form shadow is on the opposite side of the light, anwyay...
"...and darkest shadows the darkest"
You mean "darkest shadows the lowest [value]"?

Fixed :)
Every object has it colour so when light falls on it does the tone changes gradually to shade.
