Photograms and Chemigram

A photogram is an image that is created without a camera. You place objects on top of a light sensitive surface. The shadows casted from the objects creates images, but you need to chemically treat the surface to then show the images.

These pieces are created by Jennifer Morrison and are inspired by the works of Man Ray and Laszlo Moholy-Nagy

Equipment & Material

• Darkroom
• Enlarger
• Photographic paper
• Clock
• Chemicals
• Water
• Trays

Method

1. You need to set up the enlarger. set the aperture to f/8, then make sure all the filters are on zero and set the timer to 3.0 seconds.
2. Then you need to create a test strip by putting the paper, emulsion side up. Then place objects on top and using card, expose for 3.0 at a time. which is to see what is the correct exposure. 
3. Next put the strip in the chemicals: Developer for 2 minutes which needs to be agitated the hole time, Stop bath for 30 seconds, Fixer for 5 minutes and lastly the wash for 10 minutes.
4. Looking at the strip you can determine the time needed for the final piece.
5. Lastly using the new exposure time, create the  final piece by again laying objects on a bigger piece of paper then follow the same steps.

Chemigram
A chemigram uses the same method but instead of putting the pieces straight into the developer, it is painted on instead.

Health and safety

• Do not place hands in the chemicals
• clean up any spillages
• If the chemicals get splashed on to hands wash immediately
• keep the work area clean and uncluttered to prevent hazards
