Sensor Calibration

Sensor calibration, also known as , 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 HELIUM 8K S35, MONSTRO 8K VV, and GEMINI 5K S35 sensors. For more information, go to Calibrate Sensor: Manual Calibration.
• Auto Calibration: RED recommends using Auto Calibration for the DRAGON 4.5K, DRAGON 5K, DRAGON 6K, and DRAGON-X 6K sensors. For more information, go to Calibrate Sensor: Auto Calibration.

For more information, see the Sensor Calibration Methods article.

NOTE: Calibration maps are still available after performing a system restore.

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.
