Brian/Clayton,

I also forgot to ask about sharpening.  I read Clayton's workflow for BO article, and unless 
I missed it I didn't see anything about sharpening.  I've read a few different things on the 
subject, and I know it depends upon the type of sharpening, but I've always sharpened 
after resizing the photo to print dimensions.

In terms of the color/greyscale question, I guess the best way to find out is just to 
experiment.  I like the idea of saving an RGB version which would allow me to make very 
specific tweaks to the tone in ways that I'm comfortable with, and then also saving the 
flattened greyscale version prepped for proof.  I'm not too worried about file space at the 
moment, since I'm an amateur fine art photographer (not prolific) and I've got 2 500 GB 
drives to store the files on.

Thanks again for all of your help - it is sincerely appreciated.

Chris
