Lumen Printing is a relatively simple photographic process where standard darkroom paper is exposed to the sun, or other UV light source (such as my UV exposure boxes) with a variety of objects, materials or images on top.
Similar to Cyanotype and Photograms it is the light that the objects/negatives block that ultimately creates the image.

Where Lumen prints stand out is the variety of colours that can be gained, the paper itself (depending on brand/type) goes through a process of discolouration through yellows, oranges, blues, pinks, purples and browns depending on how long it has been exposed to light.
As a secondary factor if items such as sliced fruit are used the acids within also directly effect the paper creating further discolouration.
