CHAPTER 6:
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. Calibrating the sensor 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.
The camera offers two (2) ways to calibrate the sensor:
Manual Calibration: RED recommends using Manual Calibration for the MONSTRO 8K VV sensor. For more
information, go to "Calibrate Sensor: Manual Calibration" on the next
Auto Calibration: For more information, go to
For more information, see the
NOTE: Calibration maps are still 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 camera (if a lens is not attached).
4. Set FLUT or Exposure Adjust to 8.000. For more information, go to
5. 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.

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
After each firmware upgrade.
To check the temperature/exposure of the current calibration file, go to Menu > Settings > Maintenance > System
Status > Project Status.
