Then this is not good for alt. process printing. What about KRST toning?
Will be KRST toned negastives suitable for alt. process printing? Will
KRST provide any advantage over Dektol / Bromphen or Multigrade print
developers (for redevelopment)? I liked Ryuji's point: "you will
redevelop more completely with KRST: tiny grains that't won't fog in
room light and won't develop in the second developing solution (say...
in Dektol and such developers), will be developed with the toner". What
will be your comments on this?

My problems with lith negatives are: I see very ugly big black dots here
and there and general grain clumping in dense parts of the negative
(everytime) and I have high base fog (sometimes - I guess the high base
fog is caused by the fact I don't place a black sheet under the
negative). What can I do to have smoother tonality? (please note that I
use 35mm film - not medium format, so my enlargements are around 8x -
10x scale)

Thanks in advance,
Loris.
