The Image Enhancement option improves the appearance of some images by adding information to the images. This means that pixels of different colors are added to the areas of flat color to make the artifacts less visible to the eye. The appearance of the resulting images may appear softer. This option is particularly useful for images that have large areas of similar color or continuous tone, such as a large blue sky, or a single background color where artifacts may become perceptible.
By default, image enhancement is enabled. LizardTech recommends that you experiment with a variety of images to determine which images benefit from this option.
