If you use threshold as your scan option, since it is by definition a high
contrast image mode, you can only adjust the brightness of the preview
To adjust the brightness or contrast for a black and white image:
On the L60 tab, under Black and White Options, use the available slider to
adjust the brightness or contrast.
These tone adjustments are only for black and white images.  If you select
greyscale as your scan mode, you adjust the contrast and brightness of the
image only on the Tone tab.
