Preview gamma
Preview gamma applies to the image displayed in the pre-
view area of the scan window. In general, preview gamma
is solely for display in the preview area and does not apply
to the image data that are passed to the host application
when the
Scan
button is clicked. There are two exceptions
to this rule, how ev er. The fi rst is when Nikon Scan is used as
a “stand-alone” application, the second when
Use preview
gam ma
is se lect ed as the main scan gamma option. In
these cases pre view gam ma is ap plied to im age data passed
to the host ap pli ca tion.
Preview gam ma de faults to a val ue of 1.8 on the Macintosh,
2.2 on Win dows com put ers. To choose a set ting suited to
the current monitor, adjust the value so that the pat terns of
gray lines and dots above the slider match in density. Gam-
ma can be set by en ter ing a value directly into the text box or
by moving the slider. When mak ing this ad just ment, set the
res o lu tion on the monitor to a low value such as 640 × 480
and sit as far away from the monitor as possible. To restore
the default setting for your platform, click
