CALIBRATE SENSOR: AUTO CALIBRATION
NOTE: The camera cannot export calibration maps created by Auto Calibration.
The camera offers two (2) ways to calibrate the sensor: Manual Calibration and Auto Calibration. This section describes
how to calibrate the sensor with Auto Calibration.
When you start an Auto Calibration, the camera calibrates the sensor at 16 exposure settings, and uses that data to build
a calibration curve. Afterward, the sensor is calibrated for each exposure along the calibration curve, so you do not need
to re-calibrate every time you change the exposure.
The calibration process does not factor in multiple temperatures, so you will need to re-calibrate the sensor after extreme
changes in temperature.
This process can take up to 1 hour.
AUTO CALIBRATION PROCEDURE
To perform an Auto Calibration, follow the instructions below:
1. Ensure that the camera reaches the temperature that you want to use for your shoot.
2. Ensure that the sensor is as dark as possible.
Preferably, take off the lens, and install the front body cap.
If you cannot take off the lens, put a lens cap on the lens. (Not all lens caps completely block IR. Lens caps are
made to protect the lens, not necessarily to block light.)
If possible, use a dark room.
Just closing the aperture is NOT sufficient.
3. Ensure a properly formatted SSD is attached to the camera.
4. Go to Menu > Settings > Maintenance > Calibrate > Sensor > Create > Auto.
