CALIBRATION CAPTURE (BLACK SHADING)

Not including preparation time, the calibration procedure takes several minutes. To perform black shading cali-

bration, follow the instructions below:

1. Ensure that the camera reaches the temperature that you want to use for your shoot.

2. Set the exposure to the exposure you want to use for your shoot.

3. Before you calibrate, ensure that the sensor is as dark as possible.

‒ Preferably, take off the lens, and install the lens mount cap provided by RED.

‒ 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 iris is NOT sufficient.

4. Ensure a properly formatted SSD is attached to the camera.

Even if you are not saving the calibration map to an SSD, an SSD is required to store the raw images during

calibration. For more information on formatting media, see the RED DSMC Media Operation Guide available

at www.red.com/downloads.

5. Go to Menu > Settings > Maintenance > Calibrate > Sensor.

6. Select one of the following:

‒ Save As user HS: The calibration map created by black shading will overwrite the user HS calibration

map. User HS is the name for the current in-camera user-created calibration map.

‒ Save To Media: The calibration map created by black shading will be saved to an SSD.

‒ Leave both Save check boxes deselected: The calibration will only be applied until the camera is pow-

ered off, and will not be saved.

7. Select one of the following black shading options:

‒ Black Shading (Default): This option uses fixed settings which are the same settings that are used for the

factory calibration (1/48 sec exposure).

‒ Black Shading (Current FPS/Exposure): This option generates a calibration map with the currently set

frame rate and exposure. This can be used to generate a calibration for long exposures.

8. After selecting a black shading option, a dialog box displays, reminding you to cover the sensor and insert
