Used correctly, the
Gamma
setting can improve contrast while maintaining good
details for blacks and whites.
If excess ambient light washes out the image and it is difficult to see details in dark
areas, lower the
Gamma
setting to compensate. This improves contrast while
maintaining good details for blacks. Conversely, if the image is washed out and
unnatural, with excessive detail in black areas, increase the setting.
S-Curve
is an enhanced mid-tone gamma.
DICOM
is a simulated DICOM display, which can be used for training applications.
