  • Perspective drawing for a painting. A photograph automatically shows a scene with correct perspective for the location of the camera. It follows that an artist wishing to paint a picture of the scene with true perspective needs only to draw an accurate copy of the photograph. If his painting is to be of a different size from that of the photograph he must accurately scale it up or down. This may easily be done by using a Proportional Divider, sometimes called a Variscaler, set to give the scaling ratio which is required to fit the scene on to his painting support
