Hi reyalp,
          Have a look at this one (attached). I changed it to iso20 to iso200

From the sv column, this only ran from 20 to 78. As expected, there's no meaningful change in the exposure, meter bounces around between 132 and 133. Generally CHDK ISO overrides are not effective much below the stock minimum ISO.

If you run it again, I suggest setting "ISO set mode" to "CHDK" rather than script. "Script" was a test case for weird issues on certain camera.
Don't forget what the H stands for.

Sorry about that. I changed the iso set mode by mistake, later thinking that 'script' must be the default, but ........... I was wrong.
Thanks for your patience.
Try this one.
