A photograph taken close over a person's shoulder showing a seated figure in an orange-saffron garment writing with a green pen on loose white paper filled with hand-drawn diagrams of arrows and labels such as D1 through D10, with letters like T, S and D. A red book with a green cover sits on the paper beside the writing hand. On the right, a steel-topped table holds an orange insulated flask and a silver-toned ornamental rod, and another person in white trousers is seated at the top edge. The room is dimly lit with a wooden floor.
