Values - Local Value?
Okay I'm confused about what "Local Value" really is. When local value is spoken of it is often referred to as an objects physical/chemical value. Now since all values are relative, how on earth do we really know what an objects local value really is?
Is local value read from the half-tone?
And how important is it in rendering? I have the thought in my mind that a local value of an object might be say, a "4" on the value scale in a certain light, and according to the intensity of the light you subtract from that or add to it for light planes and dark planes by a step number, such as "3" for intense light or 1 for diffused light.
Am I making any kind of sense?
