The Histogram Window
Introduction
The easiest way to set the highlight and shadow points is to use the
Auto
tonal range button in the main
FlexColor
window. However, in some
cases, the auto function will not provide the desired results. The color
pickers and sliders in the
Histogram
window provide the tools you need
to fine tune your highlight and shadow points.
•
The Highlight Point is the brightness above which all input pixels will
be output at white (usually 255, unless you have set values in the
Dot
tab sheet of the
Setup
window - see "Dot Tab" on page 40 for details).
•
The Shadow Point is the brightness below which all input pixels will be
output at black (usually 0, unless you have set values in the
Dot
tab
sheet of the
Setup
window - see "Dot Tab" on page 40 for details).
You must take care when using these settings, as they can have a powerful
effect on your images. Take some time to experiment with them. Look at
the preview to see how these settings will effect the image. Save some
images after using these controls and inspect them closely. Take notes on
the kind of settings you use and make a comparative proof print.
If you do not have any experience with digital images, then you should
speak with an experienced professional, such as a scanner operator or
digital photographer, about how these controls will affect your images.
Ask him or her what to look for when you are evaluating your proof
prints. You should also read some books about digital photography,
digital imaging, scanning, and color reproduction.
