Do you really have to read the boring scientific stuff in Drawing on the Right Side of the Brain by Betty Edwards? Can you just do the exercises and get away with it? I can't really see the point in reading scientific facts about the brain and it's different parts. Is there any vital information in that text or it's all just science?
Reading is a good skill to have, it allows you to recognize thing like, oh, I don't know, IRONY.
That being said, most of the so-called "science" in DOTRSOTB is outdated at best, you're probably better off just doing the exercises.
Most of what has to do with drawing, has to do with drawing.
No seriously, if you find it interesting to know how things work in your brain, it might be an informative read, and for some, it will be an eye opener. If you are the hands-on type of learner, just do the exercises.
The whole book is really about drawing what you see, viewing reality as we know it as an abstract drawing, and copying that. Forget about all those preconceived ideas of how things are supposed to be, and copy what you see. The book gives you some useful tools, like using a viewfinder, that may also be picked up elsewhere.
However, it is just the zeroth step in learning to draw. The next steps are about learning to summarize and reconstruct reality, without passive copying, through learning gesture, constructive drawing, perspective, anatomy.
The learning process is really like destroying your pseudoskills, and then reconstructing them. That zeroth step is essential, but I really don't think you need Betty Edwards for that.
Um, no, not in this case. Edwards' "science" is pseudoscience. The brain doesn't work the way she claims.
I stand corrected, I meant to write "if you find it interesting to think you know how things work in your brain". I did a minor in cognitive psychology, and it was disappointing to learn how scientists are mostly clueless about their own brains...
