Made familiar to the public by the work of Man Ray, a photogram as the name implies is a record or drawing created with light. Typically, objects are placed upon a light sensitive surface such as photo paper and exposed to the sun or other light source. An image is formed in direct relation to the translucency the selected object(s). No camera is required. Cyanotype, van Dyke, gum bichromate, and many other printing processes are wonderful vehicles for photograms.
