Attached is a Kallitype curve I created using ChartThrob. You my find it useful as starting point for your own or for purposes of comparison. A head check if you will.

The process I created the curve under is as follows:

1. Epson R1800
2. Pictorico OHP
3. Sodium Citrate Developer
3. Gold Toner
3. Arches Aquarelle paper
4. 7 min exposure under 80 watt black light bulbs

I started out using Stonehenge Rising paper and got very similar curves, but the exposure times were long and the prints got grainy and lost a lot of density in processing. I have had a completely different experience with the Arches.

Please provide any feedback on the curve. This is my first one. So, I would like to know if it works for you or is similar to your own experiments.

The file is zipped to ensure it gets past the necessary filters etc...

Thanks,

Do you use any color negative and mat or glossy ink

I have only scanned black and white negatives for use with this process. I am not sure if that answers the first part of the question.

For ink I print using photo black (the glossy ink). The Pictorico OHP film says that you should use the glossy photo setting as a rule of thumb so I use that and have received good results.

Let me know if you need any clarification.
