Prescan Mode (LS-2000/COOLSCAN III only)

With low-contrast images,

autoexpo-sure may sometimes

fail to produce the correct re-

sults. Three options are avail-

able that allow the autoexposure operation to be adjusted for

different types of low contrast image, potentially producing bet-

ter exposure. Selecting "nega-tive" as the media type activates

a menu of autoexposure op-tions in the Scanner Extras palette

(see above). Four options are available:

• Automatic

This is the recommended setting in most circumstances, suited

to images that show a normal balance among shadows, mid-

tones, and highlights. Use a different setting only if you expe-

rience problems scanning negatives using the automatic set-

ting.

• Lo-Cont. Highkey

This setting is suited to low-con-

trast images with clearly-defined

white areas, but no clear shadows,

for example a photograph of white

clouds in a blue sky.

Reference: The Tool Chest

• Lo-Cont. Neutral

This setting is suited to low-con-

trast images in which mid-tones

predominate, with no clearly-de-

fined areas of black or white, for

example a photograph of red rose

against a green background.

• Lo-Cont. Lowkey

This setting is suited to low-con-

trast images with clearly-defined

black areas, but no clear highlights,

for example a photograph of the

night sky.
