In the video, a person is seen holding a purple light and shining it on a sketchbook. The sketchbook is open to a page with a drawing of a hand. The person moves the light around the drawing, highlighting different parts of the hand. The light appears to be a small, handheld device, and the person's hand is visible as they move the light around the sketch. The drawing of the hand is detailed, with visible lines and shading. The light casts a bright glow on the paper, making the drawing stand out against the white background of the sketchbook.
