Hi there,
this might be me again making one of my traditional mistakes but I also
use _agitation_ to control the contrast of my negs ?
So I kind of agree with Richard saying: "Contrast is a matter of
development", but in this case I fiddle the agitation - more agitation
makes contrasts sharper and YES you can easily develop to get "blown out
highlights".
In the days of yore, before The Rains came there are/were charts giving
you a "lambda" value of either .55 or 0.65/0.75 which was a contrast
measure. These were intended for peole with either condenser based or
colour head enlargers?
When you had a colourt head, you needed "harder" negs and for condenser
you needed softer ones (9,45-0,5 lambda).
Also I feel that rodinald does not only compensate "a little bit" but
actually manages quite a lot, at 1:150 or 1:300. But then you need time
for developing for an hour r so.
Love
Snoopy

is too low increase development.
