Try a drawing unit with pencils, erasures, realistic drawing, cartoons,
shading, textures, on 9 x 12 copy paper. Also, you might try making your own
slides from art books. Get up on a ladder and make a slide with ektachrome
slide film during the day. I use my zoom lens (200) and ektachrome 100 at F4
at probably 1/500 speed or 1/250. If you don't have a zoom, do it with a 50mm
and expect to crop the slide with silver tape. You can get tape at good photo
shops. The tape doesn't burn up in the projector.
Or you can make a color photo transparency at your local copy shop. It
probably cost $2.00 or less. Tell them you are an art teacher so they don't
give you a hard time about reproduction rights. Try to make the
transparencies work for you by doing more than one lesson.
