Versatile Gamma Settings
In addition to artistic and skillful lighting techniques, the use of in-camera gamma settings plays
an important role in handling contrast range and producing a specific ‘look’ for an image. The F35
and F23 offer the following enhanced gamma control options to expand such capabilities:
In-camera Creativity
(for F35/F23)
S-LOG Gamma
The F35 and F23 are equipped with an innovative
“S-LOG” gamma that can make full use of the wide
dynamic range of the CCD. The characteristics of the
“S-LOG” gamma are similar to that of a film negative,
which allows users to flexibly adjust images as they wish
in the post-production process. When the S-LOG mode
is selected, the full latitude (dynamic range) captured
by the CCDs is efficiently converted to the gamma data
using Sony’s unique algorithm, and can be transferred
as a 10-bit HD-SDI signal. This unique gamma-handling
technique allows all the image information – even in
extreme highlight areas, for example – to be maintained
so that tone can be faithfully reproduced.
HyperGamma
HyperGamma is another powerful gamma feature, which
is inherited from the HDW-F900R CineAlta camcorder.
The F35 and F23 provide four types of HyperGamma
curve: HyperGamma 1, 2, 3, and 4. Operators can select
the best-suited preset gamma curve depending on the
scene being shot and their desired ‘look’ for the image.
HyperGamma 1 and 3 enhance natural tonal
reproduction in low-key areas, while HyperGamma 2 and
4 are suitable for scenes with wide dynamic ranges.
All HyperGamma are quickly accessible via the set-up
menu.
Customizable Gamma Curve by
CVPFileEditor
™
Software
The F35 and F23 allow cinematographers to customize
gamma curves depending on their creative needs using
the CVPFileEditor gamma creation software. This
software runs on a Microsoft
®
Windows
®
PC, and enables
the gamma curve to be visually edited via an
easy-to-use GUI, simply by plotting the x and y values of
each point of the curve. Once the gamma curve has
been created, it can be easily loaded into the F35 or F23
using a Memory Stick media.
