The PowerShot S90 employs a newly developed, 10 Megapixel High Sensitivity System by combining a powerful CCD sensor and Canon's DIGIC 4 Image Processor. Thanks to this technological advancement, the S90 is dramatically more sensitive than cameras with identical megapixel counts, and delivers spectacular images with minimal noise. Increased sensitivity demands a higher ISO speed, and the PowerShot S90 delivers with a new maximum setting of ISO 3,200. Blur and camera shake are notably reduced for the ultimate in sharpness and clarity.
In addition, a new Low Light mode lets you capture images in an astonishing range of conditions. The camera automatically adjusts the ISO speed from ISO 320 to ISO 12,800 in relation to ambient brightness, subject movement and camera shake.
The PowerShot S90's RAW mode lets you shoot images without JPEG compression. It gives you clearer images and complete creative control in editing. RAW images are transferred directly to the computer where they can then be edited using image adjustment software or a processing application to adjust your images as you please. The camera can also be set to allow the simultaneous recording of both RAW and JPEG images while shooting.
Also, with 25 Shooting Modes including 17 Special Scene Modes, you're ready for whatever shot comes your way.
