[Leica] Lab vs. home processing.

[saganicc at MSKCC.ORG (Saganich, Christopher/Medical Physics)]

Some films are very sensitive to agitation with D23, in fact my experience 
was difficult. I kept reducing agitation to get the CI down.  Once you get 
it where you want it, it dandy.

The formula below is for use as a single solution developer. I only 
resort to 2 bath development when I'm dealing with seriously high 
contrast along with shadow detail that must be recorded. Single bath 
D-23 is best used undiluted. All but extreme highlights will hold.
