"Learning to draw is really a matter of learning to see --see correctly-- and that means a good deal more than mere looking with the eye." (Kimon Nicholas: The Natural Way to Draw)
To make art, one can not simply look at something. The mind analyzes what we see and simplifies details we do not need. Drawing and art requires us to perceive objects, not just see them.
"The mind's eye creates the image we see, and these are the images we attempt to represent in drawing." (Francis D.K. Ching: Design Drawing)
Drawing is more than what we see or perceive, it is about what we imagine and create in our minds.
"All drawings communicate to the extent they stimulate and awareness on the part o those who view then. Drawings must catch the eye before they can communicate or instruct. Once they engage the viewer, they should assist their imagination and invite a response." (Francis D.K. Ching: Design Drawing)
Art speaks. Every line, dot, brush stroke, and curve has a meaning and a purpose. There is a story being told by art and it is the viewers job to read it.
