Subject: Colour of Van Dyke Prints...
 
Yesterday I was making some Van Dyke Prints using the formula from
Worobiec/Spence:
 
Solution A: Ferric ammonium citrate 6g + 22ml water
Solution B: Silver nitrate 2,5g + 22ml water
Solution C: Tartaric acid 1g + 22ml water
I use destilled water for mixing it.
 
One part A + one part C mixed together an then one part B drop per drop
mixed to the solution.
 
For exposure I use a 8 UVA- 8W lamps with about 25cm away from the paper.
Exposure time was about 5-7 minutes.
 
Developing was in clear water (roomtemperature).
 
All my prints are light brown to orange….no the blackbrown I was expecting.
How can I get those black brown prints, like they are shown in the book.
More exposure?
Other Formula?
Developing in warm water?
I did not fix the prints, will I get a darker brown if fixed?
 
Thanks very much for your help,
Lg
Christina
