My topic today is the analogue photography, camera less Chemigram !

If photography is a process, classed as drawing with light. A chemigram is drawing with light and chemicals and does not require the use of a camera. They can be created in daylight, applied to a surface with light sensitive emulsion, like photo paper, and with the use of liquids, of various viscosity's, delay the moments of exposure. The process was invented by Pierre Cordier (born 1933 in Brussel) by combining the physics of painting: varnish, wax and oil in 1956.

The practice is sub-divided into 3 categories.

1: Chemigram without resist = developer and fixer are applied directly to the paper and exposed to light.

2: Chemigram with resist = the photographic paper will be coated with resist and then passed forth and back in the developer and fixer. The mask will gradually come off and form an image.

3: Chemigram with resist applied by photographic process = the photographic paper will be coated with resist, through a photographic process, like silk screen printing with photo emulsion.

And there is the option of all 3 categories being applied to one image. The chemicals used, effect the tones exhibited by the paper. Even if the exact same steps are followed each time, there is this non-deterministic behavior, that the outcome will be considerable different from one image to another.

I like to use: honey, fairy liquid, glue, latex, soil, jam, coffee, syrup, alcohol, tooth paste,
