Sketching From The Model

Photos cannot show the depth and luminescence of the source like a model because the camera flattens and distorts the image it compresses as it processes.

I don't use line drawings when I sketch organic scenes and objects. I sketch blocks of values and directions I observe from the angle of my view. I am not interested in accuracy, realism, or even if it makes sense. I just am touring the overall plane I see in the model merged with the images I have in my mind.
