Combination Photogram- Negative printing


The images created for the Codes of Survival project, and Adze to Coda, I use a combination of two photographic techniques,  traditional photographic enlargements made from standard negatives and the photogram where objects are laid directly on the photographic paper. To print a combination of both on one piece of photographic paper demands considerable skill, patients and a little bit of  luck. Because of this each image is a unique print. 

1.

There may be many ways of achieving this but this is the way I worked for Codes of Survival. The combination technique requires that the photograph aspect is enlarged and correctly exposed from a traditional photographic negative onto the paper first.

In the normal manner I established the size the photographic image was to be, made a series of test strips and work prints. I noted this information, the height of the enlarger head, exposure time, f stop etc. for later.

I lined up the projected negative on the base board so it fell exactly where I wanted it on the size paper I was going to use. I carefully cut a cardboard template that allowed me to line up any negative, (keep the insert as you need this for this for the centre) for future prints and also to line up the insert to block any stray light falling onto the area of the paper where the photogram will be exposed.

I had to cut 4 templates to get one that worked exactly.
