Hi Jacques,
I noticed that Kallitypes, at least mine, do not have much exposure range and
solarize easily!
I am using this effect and printing some very contrasty negatives reverting
tones in the shadows.
My combination paper/sensitizer gives me 10 steps in the stoufer scale, how
long are you getting?
Also, the image reversed completely in the fixing bath?
I notice some tone lost in it but not that far. May be I am using a much
weaker fixer, mine is a 5,6 % Hypo solution with 2 ml of strong ammonia per
liter.
