9 3. Calibration Operations: Overview of Calibration Operations
Calibration Types
Color Calibrator performs calibration according to the display mode (HDR or
SDR) of the display and the luminance management operating mode (Mode A or
Mode B). It supports the following four types of calibration according to the
combinations of the display mode of the display and the luminance management
operating mode. · HDR & Mode A · HDR & Mode B · SDR & Mode A · SDR & Mode B
Display mode of the display
Select the type of calibration according to the display mode (HDR or SDR) of
the display used when shooting.
HDR
When the display mode of the display is HDR, display an HDR image (color
chart) and measure the color characteristics of the display and camera. This
mode enables you to calibrate color reproduction characteristics that include
HDR high luminance characteristics.
SDR
When the display mode of the display is SDR, display an SDR image (color
chart) and measure the color characteristics of the display and camera. This
mode enables you to calibrate SDR color reproduction characteristics.
[Note] With SDR, calibration performance may not be obtained, depending on the
display characteristics of the display. If calibration performance is not
obtained, it is recommended to adjust the display settings of the display or
switch to HDR operation.
Luminance management operating mode
Select the type of calibration according to the operating mode (Mode A or Mode
B) set using [Sensitivity Simulation] of a Virtual VENICE actor of the Camera
and Display Plugin.
Mode A
This is an operating mode where the deviation in optical luminance between an
actual display and camera is included in a Virtual VENICE actor. In Mode A,
the brightness of the output video from a Virtual VENICE actor changes in the
same way as the actual shooting environment, depending on the type of display
used in the virtual space. Mode A calibrates the luminance and color of the
output video of a real camera so that it matches the output video of a Virtual
VENICE actor.
Mode B (Beta)
This is an operating mode where the deviation in optical luminance between a
real display and camera is not included in a Virtual VENICE actor. In Mode B,
the brightness of the output video from a Virtual VENICE actor does not
change, depending on the type of display used in the virtual space. Mode B
calibrates the luminance and color of the output video of a real camera so
that it matches the output video of a Virtual VENICE actor.
[Note] In Mode A, the brightness of the display (inner frustum) does not
change when the 3D LUT for calibration is applied. Use Mode A when not using a
Virtual VENICE actor in the pre-vis process or when there is no need to
calibrate the luminance of a Virtual VENICE actor and a real camera. In Mode
B, the deviation in optical brightness between the actual display and the
camera is included in the 3D
LUT for calibration, so applying the 3D LUT changes the brightness of the actual display (inner frustum). The Mode B functionality is in beta. This is an experimental feature, so conduct sufficient testing before operating in Mode B.
10 3. Calibration Operations
Basic Operation
Color Calibrator and the On-set Camera component of the Camera and Display
Plugin are used for calibration operations. The calibration procedure will
vary depending on the calibration type. Perform the calibration according to
the appropriate type. For details about calibration types, see “Calibration
Types” (page 9).
“HDR & Mode A” Type Calibration
Operation
Use the following calibration procedure when the display mode of the display
is HDR and the luminance management operating mode is Mode A.
1 Set the calibration chart to “W100” in the
On-set Camera component. The W100 chart appears on the display. For details,
see “Displaying Color Charts on the Display” (page 19).
2 Check the display settings.
The display must be set to the appropriate settings for successful
calibration. Check that the display is configured as follows. · Color space
setting of the display
controller matches the color chart. · W100 chart is displayed at 100 nits
emission (check by measuring the display using a spectral radiance meter or
other device). For details, see “Configuring a Display” (page 21).
3 Check the camera settings.
Check that the camera is configured as follows.
For details, refer to the manual for the camera. · Input Color Space:
“S-Gamut3.Cine/SLog3” or “S-Gamut3/ SLog3” · Recording Format: X-OCN video
format · ND Filter: “Clear” · White Balance: “6500K” · Exposure Index: VENICE
2 8K (CineAltaV 2 8K): “800EI” VENICE 2 6K (CineAltaV 2 6K)/VENICE
(CineAltaV): “500EI” · Base ISO: VENICE 2 8K (CineAltaV 2 8K): “ISO 800”
VENICE 2 6K (CineAltaV 2 6K)/VENICE (CineAltaV): “ISO 500”
[Notes] · When an output signal from a camera is input
to Color Calibrator via SDI connection, checking “Recording Format” is not
required. · There are no restrictions on the “FPS” and “Shutter” settings, but
at high shutter speeds, flicker may occur if the display and camera are not
synchronized. · When operating using a display with a color temperature other
than 6500K, set “White Balance” to match the color temperature of the display.
4 Check the camera viewfinder settings.
The camera viewfinder must be set to the appropriate settings for successful
calibration. Check that the viewfinder is configured as follows. · Zebra
function of the viewfinder is
enabled. · Zebra display of the viewfinder is set to
zebra 2 (display level of 61%). · Output video of the viewfinder is set to
Log. For details, see “Configuring a Camera (Viewfinder)” (page 23).
5 Adjust the exposure by shooting a W100
chart using the camera. Set the exposure (61%) appropriate for shooting a
color chart in S-Log3. Adjust the shutter and iris to set the exposure so that
the zebra appears on the W100 chart when viewed in the viewfinder. The zebra
is displayed when the exposure is 61% or higher. When the exposure is set such
that the zebra starts to appear, the W100 chart will be shot at 61% exposure.
6 Set the calibration chart to “HDR1” in the
On-set Camera component. The HDR1 chart appears on the display. For details,
see “Displaying Color Charts on the Display” (page 19).
[Note] Check that the color space setting of the display controller matches
the color chart.
7 Shoot and record the HDR1 chart using
the camera. Shoot the HDR1 chart using the camera and record to a file in
X-OCN format. Observe the following when shooting the color chart. · Turn off
all lighting in the shooting
location and do not use any lighting other than the display. · Check that
nothing is displayed in the outer frustum surrounding the chart display area.
If anything other than the chart is displayed, it may be reflected onto the
chart and affect the accuracy of calibration. · Place the chart in the center
of the display screen, leaving some space around the chart. When shooting,
this helps suppress the effects of peripheral light reduction of the lens.
· Make sure that the chart is not in focus. If you are focused on the display
surface, moiré may occur.
When an output signal from a camera is input to Color Calibrator via SDI
connection Calibration is performed by direct input of the video captured by
the camera, so there is no need to record to a file.

“SDR & Mode B” Type Calibration
Operation
Use the following calibration procedure when the display mode of the display
is SDR and the luminance management operating mode is Mode B.
1 Set the calibration chart to “W100” in the
On-set Camera component. The W100 chart appears on the display. For details,
see “Displaying Color Charts on the Display” (page 19).
2 Check the display settings.
The display must be set to the appropriate settings for successful
calibration. Check that the display is configured as follows. · Color space
setting of the display
controller matches the color chart. · W100 chart is displayed at appropriate
luminance emission (check by measuring the display using a spectral radiance
meter or other device). For details, see “Configuring a Display” (page 21).
3 Check the camera settings.
Check that the camera is configured as follows. For details, refer to the
manual for the camera. · Input Color Space:
“S-Gamut3.Cine/SLog3” or “S-Gamut3/ SLog3” · Recording Format: X-OCN video
format · ND Filter: “Clear” · White Balance: “6500K”
14 3. Calibration Operations: Basic Operation
· Exposure Index: VENICE 2 8K (CineAltaV 2 8K): “800EI” VENICE 2 6K (CineAltaV
2 6K)/VENICE (CineAltaV): “500EI”
· Base ISO: VENICE 2 8K (CineAltaV 2 8K): “ISO 800” VENICE 2 6K (CineAltaV 2
6K)/VENICE (CineAltaV): “ISO 500”
· FPS: “23.98”
· Shutter (angle): “180”
· Iris (T value): “T4.0”
[Notes] · When an output signal from a camera is input
to Color Calibrator via SDI connection, checking “Recording Format” is not
required. · When operating using a display with a color temperature other than
6500K, set “White Balance” to match the color temperature of the display.
4 Set the calibration chart to “SDR1” in the
On-set Camera component. The SDR1 chart appears on the display. For details,
see “Displaying Color Charts on the Display” (page 19).
[Note] Check that the color space setting of the display controller matches
the color chart.
5 Shoot and record the SDR1 chart using the
camera. Shoot the SDR1 chart using the camera and record to a file in X-OCN
format. Observe the following when shooting the color chart. · Turn off all
lighting in the shooting
location and do not use any lighting other than the display. · Check that
nothing is displayed in the outer frustum surrounding the chart display area.
If anything other than the chart is displayed, it may be reflected
onto the chart and affect the accuracy of calibration. · Place the chart in
the center of the display screen, leaving some space around the chart. When
shooting, this helps suppress the effects of peripheral light reduction of the
lens. · Make sure that the chart is not in focus. If you are focused on the
display surface, moiré may occur. When an output signal from a camera is input
to Color Calibrator via SDI connection Calibration is performed by direct
input of the video captured by the camera, so there is no need to record to a
file.
6 Shoot and record the “SDR2” and “SDR3”
charts.
Repeat steps 4 to 5 to shoot and record
the SDR2 chart and SDR3 chart in the same way.
7 Access the X-OCN files recorded in step 5
from the computer running Color Calibrator. If direct access is not possible,
transfer the files to the computer. When an output signal from a camera is
input to Color Calibrator via SDI connection Input the video shot by the
camera directly. Access to files is not required.
