"Back To Basics" continued

I'm trying out a few exercises I may do with the 

"Back to Basics" class I'm teaching in January.
I'm starting with one from Peggi's Value and Color DVD.

 I took the drawing of the sphere and block,

and massed in everything in shadow in one color.  

I adjusted the shadow values, 

then moved on to the masses in light.

The whole time I reminded myself about 

cast shadows, form shadows, 

shadow core, reflected light, 

half tones and accents. 

Then, I took two objects similar to the sphere and cube; 

a yellow cup and a red box, 

and painted them in color, using the same approach. 

This is an incredibly valuable exercise.

A good drawing and a clear understanding of those terms

(and how they help suggest form) 

are the foundation for strong paintings. 

I need to get really comfortable with this. 

before I have to demo it in front of the class!
