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.
