Michael, thanks for clarifiying about the order in which the samples are to be read. There is a file (QTR-21X4-Random) in the EyeOne folder that shows the A1-4 then B1-4 order. That is what I based my comment on, so its good to know that either way works. I'm also glad that the other information was useful. It's nice to have repaid a bit of the help I've received via this and other photography fora.
