The only pre-requisite for the workshop in Montana is that you come ready to learn, and that you be prepared to work.

The carbon workshop will cover the following.

1. How to make your own carbon tissue. Although there is currently a source for commercial carbon tissue (Bostick and Sullivan) my belief is that a person who really wants to take full advantage of the carbon process should want to learn to make his/her own tissue. The ability to do so expands the range of print colors as well as surface qualities as regards relief effect.

2. Sensitizing the tissue with dichromate, using both the tray method of immersion (potassium dichromate) and the spirit method of brushing on (ammonium dichromate).

3. Preparing the negative for exposure and exposing using UV light source.

4. How to transfer the exposed tissue to a final support.

5. Developing the image in warm water.

6. Final finishing of the image. Drying, retouching, etc.

There will also be some discussion of how to optimize our negatives for carbon printing, using both in-camera and digital types. However, the focus in this effort will be practical to give immediate results since the workshop should focus on carbon printing itself, and not sensitometry or Photoshop manipulation. I will of course provide a list of the things that people should bring to the workshop, and to a certain degree those who can bring suitable negatives will have a leg up on the learning process.

Hi Tsuyoshi, Joe,


If you will provide me with your snail mail address I will send you a small sample of a carbo print with very high relief to give you an idea of what we will try to achieve at the carbon workshop. Most people have never seen a real carbon print, much less one with high relief, so you might find this interesting.

Best,

Sandy
