Interesting script... let's test it...Canon A570IS on AUTO,1. Auto High ISO, shot taken at ISO 8002. Auto High ISO, script shot at ISO 800 - barely a difference3. Auto ISO, shot taken at ISO 2004. Auto ISO, script shot at ISO 200, longer exposure, looks nice and sharp.The pictures have the original EXIF. It is a better way to get what you see in terms of metering, but the exposure time will kill you. Don't expect this to work in hand free or moving objects scenes. I go manual usually, so I won't really use this script, great job anyway! Tested when using the flash, it increases the exposure time from 1/60 to 0.6 and lowers the flash output. Nice color range, might change my mind about it...

With ISO override (Extra Photo operations) I was able to get the 'commercial' ISO 1000, with a real ISO I think around 5-600. Lowest ISO that made a difference was (real) 40. An interesting side-effect was that the commercial ISO was written to EXIF.I think these are the usable ranges for A450/A460, though the picture at '1000' ISO is not much of use in the dark.
