Calibrate Sensor: Manual 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 Manual Calibration.
When you start a Manual Calibration, the camera calibrates the sensor at the current exposure and temperature setting. You will need to re-calibrate the sensor after extreme changes in exposure and temperature. The Manual Calibration process takes several minutes.
Manual Calibration Procedure
To perform a Manual Calibration, follow the instructions below:
- Ensure that the camera reaches the temperature that you want to use for your shoot.
- Set the exposure to the exposure that you want to use for your shoot.
- 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.
- Go to Menu > Settings > Maintenance > Calibrate > Sensor > Create > Manual.
- Select how many calibration maps that you want to create from the Number of captures drop-down menu. You can create up to four (4) calibration maps at a time.
- Select the exposure that you want for each calibration map from the Capture drop-down menus.
- Select Start Capture(s).
- Select OK on the dialog box that opens. The system initializes and then makes multiple passes through the following phases of the calibration:
- Capturing
- Analyzing
- Erasing
- Programming
- When the Calibration Successful dialog displays, select OK to complete the process.
The new calibration map is automatically selected.
