Shadows are complex. There are hard shadows and soft shadows, which Brenda characterized as cast shadows vs. form shadows. The edge of the shadow close to an object is harder-edged than the edge of the shadow farther away. Then there is the color of the shadow--it should be a darker shade of whatever surface on which it is cast, but so many variables come into play--the color of the object casting the shadow reflects onto the surface; light bounces to create unexpected pockets and edges of light; the intensity of the light dictates the intensity of the dark. We looked at all of these things today in a fantastic demonstration, and then we tried things out for ourselves. We proceeded as previously--made a contour drawing, then painted it--but then we took our objects outdoors into the intensity of the afternoon sun (the overhead fluorescents indoors not giving us much) to experiment.
