CALIBRATE
The Calibrate menu includes: Sensor, Gyro/Acc, and Lens.
SENSOR CALIBRATION
Sensor calibration, also known as black shading, is a process during which the camera optimizes image
quality by ensuring that pixel sensitivity remains consistent throughout the sensor. Black shading generates a
calibration map based on system and environment settings.
After calibration, the sensor shows a uniform noise profile over the whole area without any falloffs on any side.
For more information, see the
article, available at
NOTE: Calibration maps will still be available after performing a system restore.
CHECK NOISE PROFILE
To check the current noise profile, follow the instructions below:
1. Ensure that the camera reaches the temperature you want to use for your shoot.
2. Set the exposure to the exposure you want to use for your shoot.
3. Put a lens cap on the lens (if a lens is attached) or a front body cap on the BRAIN (if a lens is not attached).
4. Go to Menu > Settings > Look > FLUT.
5. Set FLUT to 8.000.
6. Check the noise that displays on the monitor:
‒ The noise is random, with no fixed patterns or lines. The sensor is calibrated.
‒ The noise has patterns or lines. Calibrate the sensor. For more information, go to
WHEN TO CALIBRATE SENSOR
Calibration is required:
After an extreme change in temperature (+/– 30°F or +/–15°C) from the current calibration map.
After an extreme change in exposure time (+/– 1/2 sec) from the current calibration map.
If either the T or E in the CAL: T/E indicator is not green.
If the noise profile shows patterns or lines. For more information, go to
“Check Noise Profile” on page 104
For EPIC DRAGON or SCARLET DRAGON: After each firmware upgrade.
For EPIC MYSTERIUM-X or SCARLET MYSTERIUM-X: After a firmware upgrade if instructed to do so in the
firmware release notes.
To check the temperature/exposure of the current calibration file, go to Menu > Settings > Maintenance > System
Status > Calibration.
