In order to learn how to draw you must first learn how to see. You have been spending most of your life looking, but not truly seeing. The viewfinder will change that…
You will cut out a template using the manilla folders, then attach them together with one paper clip at the top.
Here below is one of Vincent Van Gogh’s early drawings before he began using the viewfinder. Notice how flat and one-dimensional this drawing is.
Below is another drawing, done just 2 years later after training his perceptions with the use of a simple viewfinder (similar to the one you will build). Notice the change in depth, line and perspective!
