Digital BW, The Print

Thanks for the response.  

How much memory is needed under Windows 2000 for the best resolution 
of a 2-1/4 square negative, B&W and Color?

You indicated that the Sprintscan 120 outputs in 12 and 14 bit mode.  
I'm not too literate on when one would use one mode over the other, 
but how is it that Photoshop supports 8 & 16 bit and the Polaroid 
outputs in 12 and 14 bits?

I gather that this isn't a problem scanning into photoshop, but how 
does it work?  MY HP S20 scans in either 8 or 16 bit, so the 
compatibility to Photoshop is clear.  Does Photoshop automatically 
convert it to 8 bit, or what?  How's it work with the Piezography 
software? 

Thanks, 
George
