A photograph made by placing things on light-sensitive paper and then exposing it to light is called a photogram. This is what was called a photograph in older times, when this was the only method of making a picture. Today, a photograph is typically what you see when you take a photo on a camera. Another word for a photogram is cameraless photography.
This creates an interesting picture. It’s more often abstract, and there are three distinct shades to the pictures. Black areas received full light. Grey areas were exposed through transparent or semi-transparent objects, like a glass or marble of some kind. White areas were covered by opaque objects that let no light through to the paper underneath the object.
