Yes, I've been seeing them in order, and I now see in your third message that you changed to another file in CMYK! I guess I was looking for your confirmation that you saw the right data in the YCbCr file, and I missed that the discussion switched to the CMYK file because the subject line mentioned YCbCr. I'll try to keep up with the big dogs from now on - or maybe I just need to stay on the porch! Thanks, Gene
