The Advanced Color Tab
The Advanced Color tab contains the fol-
low ing items:
Black Auto-Contrast clip
By default, the black point is set to a value
that excludes 0.5% of the darkest pixels
in the crop. This produces an optimal dy-
namic range, with minimal loss of detail in
shadows. To preserve detail at the expense
of dynamic range, choose a lower value
(choose 0 to set the black point to the dark-
est pixel in the crop). To increase dynamic
range at the expense of detail, choose a
higher value.
White Auto-Contrast clip
By default, the white point is set to a value
that excludes 0.5% of the brightest pixels in
the crop. This produces an optimal dynamic range, with minimal loss of detail in highlights.
To preserve detail at the expense of dynamic range, choose a lower value (choose 0 to set
the white point to the brightest pixel in the crop). To increase dynamic range at the expense
of detail, choose a higher value.
Black Dropper value/White Dropper value
Controls the default output values for white point and black point. Output for each chan-
nel can be set to a value between zero and 255; these settings can also be adjusted in the
Curves window. By default, output levels for the white point are 255 for each channel, which
displays as white on most computer monitors. The defaults for the black point are 0 for each
channel, which displays as black.
Dropper sample size
This setting determines the size of the area sampled with the eyedropper cursor in the White
Balance and Curves palettes. You can select a sample sizes of Point Sample (the default
setting), 3 × 3 Average, and 5 × 5 Average. When the sample size is set to 3 × 3 or 5 × 5, the
average for the pixels sampled is used. Choosing a large sample size reduces precision, but
also min i miz es the effects of noise; choosing a small sample size has the op po site effect.
