Notes on SD Override for the ELPH100
SD overrides will only work when the camera is in AFL mode ( auto focus lock ). To activate AFL :
- The camera must be in Program mode rather than AUTO (slide switch on top of camera).
- You must be in normal Canon shooting mode (not CHDK <ALT> mode)
- Press the "left/flower" button after first "half pressing & holding" the shutter release button.
If you complete the above 3 steps correctly, you should see the Canon software put the letters AFL on the upper right edge of the LCD.
