Using a photograph of an interior space is great tool to for drawing a realistic interior. Connie Riik, a local interior designer, allows me to use her interior design images for my inspirational visuals. This finished one-point perspective line drawing comes from the photograph below. First I printed out the photograph in 8 1/2″ X 11″ and then divided this with a grid. I use this for my proportion and visual guide for the drawing. The room image is set up as a one -point perspective with the flat back wall. Notice one piece, the chair and ottoman, is positioned in a two-point perspective.
