Photograms and Cyanotypes

Photograms

A photogram is produced directly on a light sensitive surface without a camera. Here a piece of Black and White photographic paper has been placed under an enlarger and using a poppy petal as a 'negative' the image is exposed.

Cyanotype

A cyanotype is made using UV light to produce an image on paper sensitised with iron salts.
