Overview 3
Overview
Cameras of the Sony CineAlta series are equipped with
the User Gamma function, which enables users to set
desired tone curves at will, using the gamma
compensation capability.
CvpFileEditor is a tool for freely creating and controlling
the gamma compensation characteristics of the cameras.
Cameras on which gammas created by
CvpFileEditor can be used
• HDC-900 series (AT Ver. 1.3 or later)
• HDC-F950
• HDW-F900 (AT Ver. 2.xx or later)
• HDW-F900R
•F23
•F35
• HDC1000 series (optional HZC-UG444 required)
Gamma Compensation
For compensation for smooth contrast
characteristics as a successor to knee
compensation
Knee compensation is a function to compress the contrast
for high luminance by a polygonal curve. As the contrast
characteristics sharply change at the turn-off point of the
polygonal curve, a point may be visible on a subject that
has smooth gradation. In addition, skin color of high
luminance is prone to coming out yellow.
By setting user gamma, smooth gradation can be
reproduced without sharp turnoff that may be seen with
knee compensation, while maintaining high-luminance
contrast.
Optimum characterizing according to the
dynamic range of each camera
The F23/F35 Digital Cinematography Cameras can have
a dynamic range of 800% at maximum, enabling contrast
reproduction at higher luminance than conventional
cameras of 460% dynamic range.
The User Gamma function enables creation of the
optimum gamma curve according to the dynamic range of
each camera.
Optimum characterizing for postproduction
With a curve set for usual video materials to mainly
compress high-luminance contrast, color grading for high
luminance is not sufficiently allowed.
User gamma setting permits you to decrease total contrast
for easy postproduction processes.
Image creation by directly adjusting camera
outputs
If direct outputs from the camera are used without
assuming postproduction, user gamma can be used as a
function for real-time tone control.
Major Functions of CvpFileEditor
Management of gamma data and user gamma
files
You can manage created gamma data with a list.
As the data can be grouped as a user gamma file to install
in a camera, it is easy to replace gammas in a camera,
depending on shooting scenes and conditions.
A title and various comments can accompany your
gamma data, which can be used as a reminder of the
recording condition or tips when editing other gamma
data.
Strongly enhanced curve editing functions1)
Parameter Edit mode is added to automatically create an
optimum gamma curve by specifying some major
parameters that determine the gamma. You can arbitrarily
specify elemental parameters, such as dynamic range,
white limit, 18% gray (middle tone), black level, and
initial gain. You can also intuitively change these
parameters by operating a graphic display with your
mouse.
Custom Edit mode is also available for more detailed
gamma data editing, permitting you to freely edit without
parameter setting.
Unlimited hyper gamma setting1)
As a function for parameter editing, hyper gamma can be
selected. Hyper gamma is a gamma curve based on an
algorithm unique to Sony. It reproduces natural contrast
and colors from middle tone to high luminance on a
monitor screen.
It features convenient adjustability to record images to be
used as-is for video materials or as raw materials to be
processed in postproduction.
Direct transmission of gamma data via
Ethernet1)
In addition to the conventional installation method that
uses a Memory Stick, created data can be sent in a few
seconds to a camera (if it is F23 or F35) via Ethernet for
checking the characteristics of the curve on the spot. This
may be especially convenient for real-time process of the
tone curve according to subjects.
Renewal operation displays1)
All the graphical windows are newly designed to enable
management and editing operations for gamma data, as

well as transmission to a camera in the respective
windows.
Window tools, such as Zoom Manager for easy graph
scaling, are also included.
Mutual data conversion with other color grading
tools
1D LUT data, often used in postproduction, can be
imported and converted to a user gamma for your camera.
Conversely, user gamma you create can be exported as 1D
LUT data for other systems.
Defining the bit length and output of inverse gamma data
are also enabled.1)
Smooth transition from previous versions
Application data (*.cfe files) created with a previous
version (V2.2 or V3.0) of CvpFileEditor can be directly
read and converted for usage. You can start curve
processing using data you created before as the base.
The file saving format of V4.0 is *.ce2.
1) Functions newly added in V4.0
System Configuration
You can create gamma data using those of other systems,
the built-in library, or the parameter edit function. The
created data can be installed in a camera via a Memory
Stick or Ethernet.

_ Base Curve Select the basic characteristics
of the curve.
Hyper Gamma: To use hyper
gamma as the base, which
provides the middle tone with
characteristics close to ITU-
R709 optimum for video
monitoring and whose high
luminance area is naturally
compressed, achieving
superior gradation expression
and color reproduction. This
setting is also used for
shooting that assumes color
grading processing in
postproduction.
Log: To set characteristics close
to the sensitometric
characteristics of negative film.
This setting is used for digital
processing in postproduction
equivalent to digital image
scanning for film.
Power: To set the characteristics
close to those of the luminance
reproduction of a CRT.
Characteristics near the built-
in ITU-R709 or INITIAL 5.0
characteristics are provided.

Functions and Operations of the Component Windows

dOption selection check boxes
Black Clip Off
To turn off the Black Clip function that limits video
characteristics on the minus side. Checking the box opts
for the characteristics on the minus side to be output. Use
the output of characteristics on the minus side to maintain
the characteristics for noises. When you use this option,
note that proper display may not be obtained on other
monitors. Normally it is recommended to set the black to
3 to 5% and not use this option.
Gamma Fix
To inhibit the gamma gain and step gain functions of
cameras. Sony cameras are equipped with these functions
for fine adjustments of gamma, mainly ITU-R709-based
gammas.
As these functions may not operate as precisely as you
intend when using hyper gamma or Log-based gamma
having a wide dynamic range, it is recommended to check
this box to turn the option ON.
Knee Off
The Knee Off function forcibly turns off the Knee
function of a camera. The purpose of this option slightly
differs between the types of gamma data.
Type 3.0: It is recommended to turn this option ON to
prevent the Knee function from inadvertently being
turned on when you have created a gamma curve for
usage that does not require the Knee function.
Type 2.0: As a camera of this data type has a limitation in
creating a high-luminance gamma curve, use this
option to create the curve with the Knee function
activated (see the figures shown on the next page).
It is recommended to turn this option ON when
creating a gamma curve having a wide dynamic range.
D-Range To specify how much of the input
light intensity (dynamic range) of
a subject to be used for output.
To use a wide range, set it to
600–800%. When a large value
is specified, the middle
luminance (18% gray) is
decreased. To increase the
middle luminance, set the
dynamic range to 400% or less
or increase the 18% Gray
setting.
The dynamic range of HDW- and
HDC-series cameras is 460% at
maximum. That of F23/F35 is
800% at maximum.
White Limit To set the upper limit of the high-
luminance output. The setting
must be the output level
corresponding to the White Limit
setting in postproduction or a
camera system.
Note
This adjustment determines the
white clip of the gamma curve.
To use the value you set here,
turn the white clip of the camera
off.
18% Gray To change the luminance of
middle tone. Set the output level
with respect to the input level of a
test chart of 18% reflection.
Note
If Hyper Gamma is selected for
Base Curve, you cannot specify
it by a numeric value. Move the
icon on the graph, using the
mouse or arrow keys.
Black Set this item to include the
master black level of a subject in
the gamma. Normally set to 3%.
You can achieve the same
adjustment using the built-in
master black function of a
camera.
Initial Gain To specify the gradation
expression for black parts.
Normally set to 4.5- to 5-times
gain.
To improve the S/N at black parts
or emphasize the middle tone,
select a small value.
_ Gain To decrease the total level while
maintaining the characteristics.
You can select among from four
values; 0 dB, –6 dB (–1 f-stop),
–12 dB (–2 f-stops), and –18 dB
(–3 f-stops).
