Description
I had a request for help on chiroscuro, which is basically a method of using value contrast to describe the form of an object. The most basic exersise I can think of is to draw a styrofoam shere (or egg, ball, cup, whatever as long as its white) with charcoal using a single light source (spotlight or window) coming from the side and slightly above. Look carefully at the object. Watch for the highlight, lights, mid-tones, core shadow (the dark area where the sphere turns away from the light into the shadows), and finally the reflected light bouncing back. The cast shadow usually has the darkest value and starts with a crisp line that gradually blurs and fades. Just for fun (I'm easily amused ) you could move the cast shadow about an inch under the object and make the sphere hover. This is a basic tutorial, I know many of you may already know this stuff, but hopefully some will find it helpful have a nice day P.S. materials used- vine and compressed charcoal, kneaded eraser, tissue paper
