Start with The Keepers of Light formula for Van Dyke printing, but use =
brown instead of green ferric ammonium citrate.
To 12ml of the prepared solution add:
3ml of gum arabic (with or without pigment)
3 drops of HC110 ( the very concentated solution, as it is sold by =
Kodak)!!!!!!!?
2 drops of potassium dichromate saturated solution
Develop in water, or for really crazy effects in a highly diluted =
solution of Dektol ( 1:50).
Fix as for other Van Dyke prints.
(By the way can someone tell me why this works when in fact it should =
not?)
Yes, after 40 years of photography (I started when I was 6), "the ready =
interaction, the improvisation, discovery, the benefit of trial and =
error" as Judy puts it so well, still makes photography more and more =
interesting everyday.
