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?
