DIGIC III Image Processor
With DIGIC III, your images boast superior quality, the camera operates at top efficiency and battery life is enhanced. What’s more, DIGIC III enables Canon’s Face Detection Technology and Red-eye Correction to give you better, more true-to-life people shots. Simply press the Shutter Button halfway down, and the camera automatically pinpoints the faces in the scene and chooses the ideal focus point. The camera controls exposure settings and flash to keep every face looking bright and natural. Red eyes can be corrected during playback

DIGIC III features Face Detection technologies, giving the you best possible results in any shooting situation. Face Detection AF/AE sets the focus point and exposure for the faces of your subjects. Face Detection FE adjusts the flash to correctly illuminate your subject to provide the best balance between your subject and the overall scene, eliminating the common problems of over- and underexposed faces

Red-eye Correction detects and corrects red-eye during playback. In unusual cases where red-eye is not automatically detected, it can easily be corrected manually during playback mode.

The PowerShot A720 IS features ISO 1600 and High ISO Auto settings that reduce the effects of camera shake and sharpen subjects in low-light situations, giving you greater shooting flexibility

iSAPS Technology is an entirely original scene-recognition technology developed for digital cameras by Canon. Using an internal database of thousands of different photos, iSAPS works with the fast DIGIC III Image Processor to improve focus speed and accuracy, as well as exposure and white balance.

Ourcamerareviews.com writes “Taking pictures on the Canon PowerShot A720 IS sure is a breeze with one of the 20 shooting modes or one of the 5 color modes. Choose between taking a classic black and white photograph, or add a little special effects to a beach or night scene shot. Whatever your situation is, the Canon PowerShot A720 IS will be able to handle it. Viewing pictures on this digital camera is just as easy as taking them with the 2.5 inch LCD screen. Mock up a slide show or make on camera edits, whatever it may be, this new Canon will be sure to leave you impressed every time you use it.

The Canon PowerShot A720 IS is simple, easy to use, hosts a variety of features and produces excellent photographs.”

bobatkins.com concludes “The Powershot A720 is is a remarkably capable camera with extensive manual options. There's very little you can't do in the way of manual control as long as you select the correct mode. You have full control over shutter speed, focus, aperture, flash power and operation, metering, AF zones, image sharpness/contrast/saturation, drive mode, image stabilization and just about every other feature the camera offers. Of course you can also operate the camera in fully automatic mode if you wish. The lens quality is good and the zoom range is useful. There can be a little purple fringing of very bright areas, but it's not excessive and it's something seen in just about all cameras of this type. The image stabilization system is very effective. Focus and exposure are consistently good. Extreme highlights occasionally blow out, but that's indicated on the histogram display and is easily corrected by shooting again with a little negative exposure compensation. For the price (under $200 from Amazon.com) I think it's quite a bargain.
What's missing? Well, a 28mm lens setting would be nice and the ability to record images in RAW mode would also be useful, but I can live without either one given the price and features of the A720is.
Note that the A570is is essentially the same camera, but with a 35-140mm zoom lens and a 7.1 MP sensor. If you don't need the extra zoom range of the 720is, you can save about $40 by buying the A570is.”
