Another cameraless image making technique I enjoy experimenting with is with lumen printing. This is the process of creating a photogram by laying an object as a “positive” on expired photographic paper and exposing the paper to sunlight. Over exposing the paper and adding elements to distress the process can create interesting effects as the image develops. The lumen prints below have been created with fresh botanical elements fom my garden and hessian fabric.
The cyanolumen process is much the same, however, one coats the expired photographic paper with light sensitive cyanotype chemicals prior to adding the subject and exposing to the sun. These images are then fixed in a chemical solution, but often I scan them prior to this as the colours can change.
