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 HELIUM 8K S35, MONSTRO 8K VV, and
GEMINI 5K S35 sensors. For more information, go to "Calibrate Sensor: Manual Calibration" on the next page .
Auto Calibration : RED recommends using Auto Calibration for the DRAGON 4.5K, DRAGON 5K, DRAGON 6K,
and DRAGON-X 5K sensors. For more information, go to "Calibrate Sensor: Auto Calibration" on page 161 .
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.
After each firmware upgrade.
To check the temperature/exposure of the current calibration file, go to Menu > Settings > Maintenance > System
Status > Project Status .
