Canon S750 - S 750 Color Inkjet Printer Application Manual page 106

Vivid Photo
If the Vivid Photo check box is selected, green and blue are printed more vividly
while the color of skin tones remains intact. This feature is useful when printing
photos containing grass, sky, or sea in the background.
Photo Optimizer PRO
If the Photo Optimizer PRO check box is selected, the color data captured by a
digital camera is corrected based on the colors and tones. This may be useful when
correcting unnatural tones caused by fluorescent lights or incandescent lamps, or
overexposure or underexposure. This Auto Photo Perfect feature automatically
adjusts the brightness, preventing extremely dark areas in an image from turning to
shadows.
