Hello & welcome ontopofm !
all pictures came out completely blacked out when overrides is ON, pictures are fine when overrides is OFF, plus the shutter speed and aperture are still 1/3200 and f8.0 eventhough they are overridden, please point me to the right settings, thanks
With fast shutter speeds you should use the flash, without flash the images taken with very fast shutter speeds will be nearly black...the faster the shutter speed you set up in CHDK the more light you'll need !
With CHDK overrides the Canon OSD always shows the lowest / highest value for lower or higher values - the Canon firmware doesn't know the "real" CHDK values, so it reports only the original, build-in data - in the pictures EXIF data this is the same...
In the CHDK OSD menu you can enabled the CHDK OSD entries:

PS: Test your fast shutter settings by shooting a bulb
