SX220 appears to behave the same. Interesting that using ISO bracketing(-400) from 3200 works without problems.

Apologies if this has been covered before, didn't find anything by searching.While testing the ISO override on the IXUS 310 HS I noticed that the camera would not accept an ISO value lower than the currently selected Canon ISO setting.So if the camera is set to ISO 3200, CHDK ISO overrides don't work.If I set the camera to ISO 400, I can override to any value higher than this; but not lower.If the camera is set to 'Auto' then all CHDK ISO overrides work (auto seems to be considered the 'lowest' ISO value).I also tested this on the G12 and SX30 and both of them behave the same way.I'd be interested to know if any other cameras work like this - or is it specific to how I've done the ports for these cameras.Phil.

in script, shooting_expo_param_override resets the override value, so calling it twice will probably not work there.There is also a bug in shooting_expo_param_override, it uses 0 to indicate the value should not be set, even though 0 is a legal value for tv96
