Reference: The Settings Window 69
In the example below, 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
High Keys: Used for images with broad highlight tonal variation but with
less shadow detail. Examples: Snow-covered landscapes; wedding gowns.
Low Keys: Used for images with broad shadow tonal variation but with less
highlight detail. Examples: Nighttime scenery; dark suits and clothing.
Underexposed: Used for images with compressed tonal variation particu-
larly in the shadow areas, characterized by an overall dark appearance
typical of underexposed positive film.
Overexposed: Used for images with compressed tonal variation particularly
in the highlight areas, characterized by an overall bright appearance typical
of overexposed positive film.
