Colour Enhancement
Selecting Colour Enhancement enables the Colour Enhancement
feature. This feature analyzes your image to improve quality
sharpness, white balance and colour density. This process may take
several minutes depending on the size of the image and the
specifications of your computer.
■ Colour Density
This setting adjusts the total amount of colour in the image. You
can increase or decrease the amount of colour in an image to
improve a washed out or weak picture.
