Van Dyke Brown #2
I’ve spent the last couple of days experiementing with the Van Dyke process.
Aside from making another step-wedge and colour-blocker exposure I have settled on a process found on the Sandy King website re: methodology.
Both the step-wedge and colour-blocker tests were done to ascertain the best starting point when using Digital Negatives. I will most likely have to do some further testing when using negatives straight out of camera.
The Sandy King methodology is as follows:
Coating
1st coat – 1+1, VDB solution + Citric acid solution
Citric acid solution = 5% or 5g/100ml.
2nd coat – VDB solution. Apply after 5 min’s of coat one drying time.
Tray One - First Wash
Water + ¼ teaspoon Citric acid/1000ml. 2 min’s
Tray Two - Second Wash
Water + ¼ teaspoon Citric acid/1000ml. 2 min’s
Toning
Tone if required.
Tray Three - Fixing
Sodium thiosulphate.
5% solution OR 50g/1000ml. PRE-MIXED
2 min’s
Tray Four - Clearing
Sodium sulphite.
1% solution OR 10g/1000ml. MIX as REQUIRED.
2 min’s
Washing
Wash minimum of 10 min’s in running water.
