Hi again Kevin, My PS is PS 7.0 which is very old[at least 10yrs], and I
certainly can't afford to update to a newer version. I'll have to find a
freeware image processor. I am using Windows 7 home premium. None
of the software that came with my 1100D seems interested in opening these files. I don't have any problems using JPEGs in registax or PS.
I have all sorts of problems using RAW[Cr2] files. Trying to learn and
remember how and where to convert from one format to another is doing
my head in, and I'm on the verge of giving up on stacking images and sticking with single exposures.
