In the Betty Edwards art book, Drawing on the Right Side of the Brain, Betty provides an upside down Pablo Picasso sketch of the ‘Portrait of Igor Stravinsky.’
I picked a different Picasso sketch, ‘Femme se coiffant — study for ‘La Guerre et la Paix’.
When I turn the reference picture upside down, the picture — in theory —becomes unrecognizable, and forcing the right side of my brain to see the lines, shapes, and spaces, that make up the image instead of the object as a whole.
