Alistair:

The Durst AC system was the last step before the minilab; they have 
integrated closed-loop color analyzers/densitometer systems.  You 
basically plug in your negative, set the computer for the focal length 
and set aperture, and the thing sets the base exposure and 
autocompensates as you raise or lower the head.  For b/w work, it's a 
little switch in units from seconds to density units, but you get used 
to it.  Exposure times are very short with a 250 watt halogen lamp.  It 
has a plug-in for a roll easel, but I figured that I could stop with 
the paper.  It's a dream for TMY, VP, PX and other straightline films, 
since the density setting is only really setting where the midpoint of 
on-paper reproduction is.

I don't print much 35mm anymore, just 6x4.5 and up.  35mm is great for 
color and something that is great to take to a frontier lab.  35mm just 
lacks the tonality and detail in b/w and spotting is a bigger, more 
annoying issue (as it is in scanning 35mm).  I do print neopan 1600 in 
B/W, since it looks better enlarged than scanned.

Split-grade?  Burning and dodging?
