Canon multipass l60 ユーザーズマニュアル

The tone of an image is its shading and combination of colours. Adjusting
greyscale tones can enhance the contrast of a greyscale image. You can
produce a wide range of visual effects for your preview image by
adjusting the different settings on the Tone tab.

If you select black and white or text enhanced as the scan mode, the Tone
tab is not available. In these cases, you must adjust the tone of the image
with the contrast/brightness settings on the L60 tab.

This section provides an overview of the Tone tab. Detailed instructions on
using the features included on the Tone tab are provided in later sections
of this chapter.
