Contrast Range
The HDW-F900R can handle a very impressive contrast
range. For the most challenging of light settings and
associated scene conditions, several useful operational
features are available that allow image optimization in
real-time to help capture the desired mood of a shot.
The first of these important functions is RGB Gamma
Balance. By changing gamma balance, it is possible to
change the color balance of the mid-tones without affecting
black and white balance. The second feature, Black Gamma,
allows fine adjustment of tonal reproduction in the shadows
(black) to be made. This can help to bring out details from
the dark parts of the picture without affecting mid-tones and
with the absolute black level remaining unchanged. It is
particularly helpful for dark scenes when the black has to
stay black, but there is a requirement to pull out more
details.
The range of creative possibilities offered by modifying RGB
Gamma Balance and changing Black Gamma is quite
inspiring and, when mastered by a cinematographer, offers a
great advantage in achieving a desired ‘look’.
