Assignment 2: Pick a single subject and a light source. Keep the subject and camera in the same place and move your light source to different places.Maybe Knott
The light above or at least at the same height is “traditional” since the sun is above, but you should feel free to experiment with it. Play with light behind, change angles around the subject. Change angle up and down. Change the way the light faces if this can be changed. So many options.
