In class we made studies of several images by painting only the pattern of the darks, leaving everything else white. when we assessed the results, much was revealed about the role the darks played in supplying the narrative content and in establishing a convincing illusion of light and space.
Now look at a new image, such as the ones below, and see what you can tell before you make any studies. Are the darks likely to make carefree work possible in the early stages? Do the middle values play an essential role in creating the feeling of depth in the scene? Which elements of the composition must be carefully rendered, and which can be handled loosely? Write down your predictions.
Then make studies that will provide answers to your questions. You might make a darks only version, or one where the middle value shapes and the whites they surround are the only forms. What did you learn? make notes on your studies, and bring them in to class.
