The 10-megapixel PowerShot SD790 IS is one of several Digital ELPH models from Canon for 2008. It offers users powerful high-end features in a compact design. The camera's 3x zoom has a focusing range from a wide-angle equivalent of 35mm to a maximum telephoto equivalent of 105mm and features Canon's legendary Optical Image Stabilization technology. Like the PowerShot SD890 IS Digital ELPH camera, the SD790 IS Digital ELPH camera features the quick and easy-to-use multi-control dial.

Though smaller than a deck of playing cards, the PowerShot SD790 IS Digital ELPH camera conveys a cool, substantial look and feel, thanks to its solid, yet streamlined, chiseled design. Adding to its appeal is the camera's large and highly visible, three-inch PureColor LCD II display, with an adjacent multi-control dial and new button configuration that combine to form a flat control panel.

Among the significant technological advances shared on the new PowerShot SD890 IS, SD790 IS and SD770 IS Digital ELPH cameras is Canon's intelligent anti-blur system. Developed by linking four of Canon's most cutting-edge achievements: Optical Image Stabilization, Motion Detection technology, Hi-ISO Auto and Noise Reduction technology, the result is consistently sharp and clear pictures, even when the shooting conditions and circumstances may not be ideal.

All three PowerShot Digital ELPH cameras feature the latest and most advanced generation of Genuine Canon Face Detection Technology, thus ensuring that up-to nine forward-looking faces in the frame - whether posed for a family portrait, candidly capturing friends and fun, or spontaneously snapping a toddler's expression of triumphant glee as two halting steps - are in focus and properly exposed, with or without flash. In addition to focus and exposure control, the camera's Face Detection feature captures truer, more accurately lit skin tones (and hence more beautifully rendered pictures) thanks to Canon's improved Face Detection White Balance. There's also a new optional "AF Point Zoom" feature that digitally enlarges the face of the main subject on the camera's LCD screen to make it easy to determine the optimum timing for clicking the shutter to capture the moment.

Canon Digital ELPH cameras offer an array of in-camera processing features that once required tweaking with computer-based photo software. Now, newly developed Automatic Red Eye Correction can be engaged while shooting, minimizing the need for correction before printing or sharing images.

With Canon's Image Inspection Tool, users can review pictures recently taken on the camera's bright, brilliant and easy-to-read 230,000-pixel PureColor LCD II display by zooming in to ensure that the subjects are in focus and to check for such picture-damning details as closed eyes or inappropriate expressions. What's more, with the digital EPH camera line's Trimming Function, users can easily crop images, centering and creating memorable close-ups whether they are smiling faces or iconic cityscapes.

The "brain" in every new Canon digital camera is Canon's proprietary DIGIC III imaging processor. This exclusive chip is responsible for the camera's higher performance levels including faster start up, faster autofocus and quicker shutter response times that leave long lag competitors far behind. What's more, the DIGIC III processor improves both the image quality and the cameras' power consumption, extending the battery life under typical shooting conditions.
