Microtek 1000xl 参照マニュアル

• Low Keys: An image with broad shadow tonal variation but with less highlight

detail. Examples include nighttime scenery, dark suits and clothing, a coal pit.

• Underexposed: An image with compressed tonal variation particularly in the

shadow areas, characterized by an overall dark appearance typical of
underexposed positive film.

•  Overexposed: An image with compressed tonal variation particularly in the

highlight areas, characterized by an overall bright appearance typical of
overexposed positive film.

In the example above, an overexposed
original is shown in two different image
categories. Because the original was
overexposed to begin with, choosing the
Overexposed image category had the
result of neutralizing the exposure,
resulting in a better image.

The same original did not fare as well
when it was assigned the 

Standard image

category (too bright overall, not enough
contrast), because this image category is
best used for originals of fairly good
quality (sharp, neither underexposed nor

overexposed) and not, in this case, for
an original with flawed exposure
settings.

This example then shows the
importance of choosing the correct
image category that corresponds most
closely to your original to obtain optimal
results.

Image assigned “Standard” image category

Image assigned “Overexposed” image category
