With CHDK the camera always starts in playback mode; press (or half press) the Shutter once or just hold POWER for ~2 seconds for record mode
As on other newer cameras with 12 bit sensors, the 'Custom curves' feature do not work on the Ixus 980/SD 990
Pressing the shutter quickly with overrides enabled may result in incorrect white balance. It may also cause issues if the flash is automatically triggered
Betas prior to build 934 needed custom grids. This has been fixed, meaning grids made for these older builds will no longer work, but standard grids will work.
