Digital BW, The Print

Anthony,

I just plain dont understand the "why: regarding your comment below, 
and if I can have this justified, I will certainly give chromogenics 
another look!
(albeit that my Nikon LS4000 + Vuescan cant be convinced to give 
sharp results; and I tried to buy Portra BW400 today to try only to 
find Kodak doesnt bring this film into Singapore... but their my 
problems!)

As background to the relevant parts of *my* workflow for colour to 
B&W conversion - RGB convert and adjust in "the imaging 
factory's" "Convert to B&W Pro 2" filter (...and for the issue at 
hand, this is comparable to using the [Channel Mixer]) with a final 
convert to greyscale for saving. Given that I'm not throwing channels 
away, where am I loosing data over a chromgenic or B&W film?

appreciated
