Digital BW, The Print

Hi,  It seems the consensus on the digital photo boards is that 
capturing in full color on a digital camera is the way to go.  One of 
the main reasons is that many people use photoshop and it has a tool 
called "color mixer" which gives great flexibility in converting to 
bw.  You get to choose the percentage of each RGB channel you want in 
your BW image.  This means that it is easier emulate the different BW 
films (or just have more room for creativity).  Once I found it I 
havent gone back to the old "convert to momochrome" tool in photoshop.
