Show Lost Highlights
The Show Lost Highlights feature identi-
fies areas in which detail may have been
lost in the highlights by locating pixels
with the maximum value for one or more
channels. This information can be used
when adjusting the tonality of the image,
such as when applying white points, to
ensure that the optimal amount of detail
is retained within the image.
When you enable the Show Lost
Highlights command, the entire image
will become black while displaying any
areas that contain maximum values
for one or more channels. Only those
areas that contain maximum values will
be displayed within the image window
when this option is enabled. That is,
only the pixels that contain a value of
255 will be displayed for each of the
three channels.
The resulting image will contain white,
primary, and secondary colors only. The
following table describes values these
colors represent:
This area contains values
White
of 255 for the Red, Green,
and Blue channels.
This area contains values
Yellow
of 255 for the Red and
Green channel.
This area contains values
Magenta
of 255 for the Red and
Blue channels.
This area contains values
Cyan
of 255 for the Green and
Blue channels.
This area contains values
Red
of 255 for the Red channel.
This area contains values
Green
of 255 for the Green
channel.
This area contains values of
Blue
255 for the Blue channel.
With this display on, you can adjust the
settings of one of the enhancements
that has already been applied to reduce
the brightening effect and prevent
details from becoming blown out.
