[Digital BW] Re: B+W Scans from RGB Scanners

John,

If that is true, why don't you see those values in the channel mixer of a directly grayscaled 
image?  If you directly grayscale an image Image>Mode>Grayscale, you can no longer 
access the image via the channel mixer. However, If you change the profile of that same 
image to RGB and go back in thru'  Image>Adjustments>Channel Mixer you will see that 
the default is 100% red.  ????? Why doesn't it read   R30% G60% B10% since those are 
supposed to be the values in each channel?
