Unlike the IXUS 300 all of the controls on the A20 are on the rear of the camera, the only button you'll find on the top is the shutter release.
|Auto record mode
This is really the "point and shoot" mode, while you still have the option to choose resolution, JPEG quality and flash mode you can only select between self-timer and single shot drive modes, macro or normal focus mode and you can't change white balance (which is set at Auto) or set an exposure compensation.
|Manual record mode
Manual record mode operates virtually identically to auto record mode except that you now have the option to select the continuous drive mode, the additional option of Infinity focus mode, change the white balance or even set an exposure compensation (+/-2 EV in 0.3 EV steps).
Designed to make shooting of panorama / stitch shots easier. You have a choice of two different stitch modes: left-right or right-left. The display changes to show previously shot frames in the sequence to help alignment of each frame. Exposure and White Balance are locked to the first frame.
