Hi Rainer,
When you ordered your raw-chemicals from 'Brenner FotoVersand' I
understand your long exposure times.
They send me the 'brown' and not the 'green' Am.-Ferric-citrate, no
idea why a specialised Photo-company sells the 'brown'-version; by
accident I mixed the 'brown' with the rest of my 'green' and my
exposure times increased from about 7 min. to more than 35 minutes
for the same neg.
By the way, I used several papers for cyano -Fabriano, Zerkall,
Hahnemuehle,Waterford, Magnani etc.- and the only one I had a yellow
stain was with the Arches paper.
cheers,
Henk
