The PowerShot Pro 90 IS offers the highest digital resolution in its class with 1,856 (H) x 1,392 (V) pixels recorded, which is very suitable for prints from postcard size to 8" x 10". Plus, you’ll get just as brilliant results from close-ups as you do from landscapes. How? Canon Know-How has developed a high-resolution all-glass lens with a 10x zoom range for near and far distances.
Canon has also added a "flash" white balance setting to the usual palette of 4 settings. But because every cloud has a silver lining, you may want to customize your own white balance. In the white paper shooting mode, you can tailor make your own white balance and store the setting into the camera’s memory even after it’s turned off.
The CCD Raw Mode preserves the image’s original quality with reversible lossless compression while enabling post-exposure manipulation of white balance, contrast, sharpening and saturation.
