Well, I FINALLY go it to work, and the images are, as I expected, JAW DROPPING!!!
I checked a check in DSS (yes Chris, I use 3.33) that I did not MEAN to (forcing interpolation) MEA CULPA, MEA MAXIMA CULPA!!!
(******** me)
OK, ignore original thread, moving right along
Interesting that DSS does not list SX cameras in the list - I had to trial several generic bayer matrices to get it perfect.
