Originally, pre-digital Camera Lucida was a 19th-century optical drawing aid that uses a prism or mirror to superimpose a "ghosted" image of a subject onto a drawing surface. It enables artists to accurately trace scenes, portraits, and still lifes, improving perspective and proportion. This iOS based Camera Lucida uses Augmented Reality to overlay images on surfaces for intuitive artistic endeavors. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
