Photography is the art of capturing and manipulating images. Photographers can use film and digital cameras as well as camera-less photography to create images.
A photogram is a photographic image that is made without a camera.
The result is a negative shadow image that shows variations in tone, depending upon the transparency of the objects used.
The process:
The shadows or silhouettes are where the objects have prevented light from reaching the surface of the paper. Areas of the paper that have received no light appear white, with areas exposed through transparent or semi-transparent objects appearing grey.
Tips:
Plan your photogram before you go into the darkroom. Where will you place objects? What objects will you use?
Make sure your photographic paper is the light-sensitive way up.
Experiment using semi-transparent and solid objects to see the different effects.
You could cut out paper stencils and shapes to use on your photogram.
A cyanotype is a photogram that produces a cyan-blue print. You do not use a darkroom to develop the image.
As with a photogram, a cyanotype is made by placing a stencil, acetate photocopy of an image, or objects directly onto the surface of a light-sensitive paper/material and then exposing it to UV light, such as sunlight.
This makes a negative shadow image that shows variations in tone depending upon the transparency of the objects used.
Areas of the paper that have received no light appear white and those exposed through transparent or semi-transparent objects appear light blue.
