Alastair, my experience with the coolscan V is that the Nikons are very 
unforgiving on denser b&w negs. (contrasty- gritty). Marty
in Adelaide recommended that I adjust the recommended development times down 
by 10 to 20% where my negs where destined to be scanned
in my Nikon. I've found the results to be a considerable improvement 
regarding the tonal range and grain reproduction. I use largely
~100 ISO films and ID11. I think that the effect of the Nikon scanners is 
more akin to a condenser enlarger.
I have no current experience regarding printing from those negs with an 
enlarger.

Cheers
Hoppy

I have spent the last 2 weekends working on my film/dev combinations,  
using the recommendations of the 205 FCC  magazine. The process is  
easy, BUT SLOW, and the results are pretty scary --- at least for me  
it explains a lot of my problems ;-)

The bottom line seems to be the EI rating of the film is a  
combination of the film and developer type. T-max 100 rates as 80 in  
ID-11 and 64 in Rodinal FOR ME. The contrast range is determined by  
the development time. You measure Zone VIII negs to give you a  
contrast range to suit your enlarger.

Does any one know what contrast range suits scanners, in particular  
Nikon 5000 !!!! Is it the density range of 1.2 as for diffusion  
enlargers or 1.01 as for condenser enlargers?

cheers
