I taught a still life class this morning. This is how I painted the subject today. You can see three types of light. The light from the lamp I used is yellowish, like all light bulb light. You’ll see hints of yellow on the tablecloth. The other kind of light comes from the window. It is blue light coming from the sky. You can see subtle blue highlights on the apples and on the tablecloth. There is also reflected light. If you look underneath the apples you see yellow reflecting from them on the cloth. There is reflected light on the cup, from the apple, the window and the light bulb.
