RE: Ammonium Dichromate

If the pigment hasn't held it could also be the exposure, Trevor...but
that does sound like a very weak mix of gum. Try changing the gum mix
first, then you cn fine-tune the exposure. You don't say what you're
using as a light source.
 I did think the brown sounded a bit - well - poo like.

I'll experiment with this, thanks...

Doh! Again (you're the third person I've confused),
this linked print is the original darkroom print which
was scanned and a negative made. Not the gum...the
second attempt is in the bath now and looking really
shabby (what you guys said about the gum not holding
the pigment is so true...i used ivory black and only
specks of it show in the highlights, the rest is baby
poo brown) But, no, i did not use a greyscale in the
scan, and the neg was made by inversion in PS. The
original was shot with Kodak HIE and printed on
Kodabrome F3.
