So in this sense contast may be obtained by completing development
to D-max on blacks and not allowing the midtones going completion.
In a simple sense the mid-tones come to completion before the
blacks reach D-Max - roughly speaking. Ending development early
results in a print where all the dark tones are a blah grey with
no detail.
If this true, dilute development without agitation may help.
Is this true?
It will lower contrast. In some papers it will turn the image
tone to a low contrast reddish brown.
Any emphasis if this true by lith developer?
Lith developer works by 'infectious development'. When used
with lithographic film tones go straight to black - it looks a
bit like a flower blooming.
When used with paper the result is barely developed mid and high
tones and patchy very deep blacks. And strange color effects -
the paper often turns pink.
Any comments before my trials?
Actually it would be best not to make any comments until
after you post what you found in your trials. Experimentation
should always be approached with an open mind.
Using a #5 contrast filter with polycontrast paper will give you
more contrast than you probably want. The only exception is if
you are looking for lots of contrast in the high-lights. I don't
know of any good way to boost toe contrast - Richard Knoppow might.
