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 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 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 “Calibration Capture

(Black Shading)” on page 101.

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.

 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.
