So I'd like to detail some art books (mostly about drawing) that are very near and dear to my heart. Some are rather difficult reads. So I make my appologies right here. However...IF you can wade through the language and set all this knowledge right in your brain, it WILL blow your mind. These are the goods right here fo shizzle. And so in no particular order....
A Treatise on Landscape painting by Andre Lhote
Painter's Progress by Maurice Grosser
The Art Spirit by Robert Henri
Figure Drawing for All it's worth by Andrew Loomis
The practice and science of drawing by Harold Speed
Oil Painting Techniques and materials by Harold Speed
Perspective for Artist by Rex Vicat Cole
The Artistic Anatomy of Trees by Rex Vicat Cole
Painting Techniques of the Masters by Hewerd Lester Cooke
Elements of Drawing by John Ruskin
more to come as I think of them...
