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 the next page .
Auto Capture : For more information, go to "Calibrate Sensor: Auto Capture" on page 121 .
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" above .
After each firmware upgrade.
To check the temperature/exposure of the current calibration file, go to Menu > Settings > Maintenance > System
Status > Calibration .
