RE: Green or Brown FAC for VanDyke
Hi David, I know a person who uses brown FAC for making Vandykes. His Vandykes are OK - nothing worse or better then what I get with green FAC. But since I don't use brown FAC and he doesn't use green FAC I can't give you a direct comparison... I don't know how is B&S brown FAC but I saw a friend's local (Istanbul) brown FAC container - it was in a from of sludge (and very sticky). I wouldn't want to deal with that (handling is not easy), so make sure that theirs (B&S) is in dry powder form (as their green FAC)... Hope this helps, Loris. -----Original Message----- From: david drake [mailto:daviddrakephoto@sympatico.ca] Sent: 07 Ocak 2007 Pazar 15:32 To: alt-photo-process-l@usask.ca Subject: Green or Brown FAC for VanDyke hello I just came across an older thread at the APUG website in which Dana Sullivan was recommending the use of Brown Ferric Ammonium Citrate for VanDyke. According to Dana, the Brown version "extends the shelf life of the solution, eliminates the white precipitate, and produces an image with considerably better mid-tone separations and not the harsh contrasty look of the Green Ferric Ammonium Citrate version" This is the first I had heard of Brown FAC and I was wondering if others were using it or had compared the two. Should I put in an order to B&S? cheers david david drake photography www.daviddrakephotography.com
