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.
The camera offers two (2) ways to calibrate the sensor:
Manual Capture: For more information, go to “Calibrate Sensor: Manual Capture” on page 101.
Auto Capture: For more information, go to “Calibrate Sensor: Auto Capture” on page 102.
For more information on sensor calibration, see the Black Shading Calibration article, available at www.red.
com/learn/red-101/black-shading-calibration.
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 camera (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.
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 100.
After each firmware upgrade.
To check the temperature/exposure of the current calibration file, go to Menu > Settings > Maintenance > System
Status > Calibration.
