CHDK specialitiesEdit

  • 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.
