For example the Kodak's 13.7 mp (4536 x 3024) high resolution
format is available *only* at ISO 80, while ISO 400 and 800 can
provide at most 6 mp (3024 x 2016) resolution.
I haven't used this camera but I think this is wrong ... for example
this review site seems to say you have the full resolution at ISO 80,
100, 125, 160, 200, 250, 320 and 400 ... only at 500, 640 and 800 are
you limited to 6 Mpix ...
