Painting with light is the process of illustrating or writing with light in a slow exposure paragraph. To paint with light you must first change your ISO to a small ISO around 100 or 200. This helps reduce noise and allows you to finish your painting. A smaller aperture will give a depth of field that is wide enough to bring in everything you paint into focal range. A longer exposure time helps capture the entire painting. Use a camera with its manual settings and a tripod to guarantee the best photo. A light source such as a flashlight, LED light, or a glow stick work for the lighting. A dark environment is the best way to get a clear picture. The person painting with light must also wear dark clothes so they cannot be seen in the picture.
