Digital BW, The Print

I'm using a Canon D30 and just recently converted my Epson 
1270 to use MIS VM inks with Paul's curves.  I used to shoot 
B&W with technical pan in a 35 mm and I think the D30 does just 
as well, if not better up to A3+.  The RAW files are 17 meg 16 bit 
and not 8 bit.  I've used both Genuine Fractals and the various 
step intepolation actions and it seems to be a toss up in terms 
of quality - at least when resizing up to 12x18, which is as large 
as I go.  The quality and tonal range possible with the VM inkset 
is really outstanding.
