After an extreme change in temperature (+/- 30 °F or +/-15 °C) from the currently selected calibration map.
After an extreme change in exposure time (+/- 1/2 sec) from the currently selected calibration map.
After a firmware update.
To check at which temperature/exposure time the currently selected calibration was taken, go to Settings >
Maintenance > System Status > Calibration .
For more information about black shading, check out the Black Shading Calibration article available at www.

NOTE: Calibration maps will still be available after performing a system restore; however the factory calibration
map will be reselected.
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 media, an SSD is required to store the raw images during
calibration. For more information on formatting media, go to “Manage Digital Media” on page 108 .
5. 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 external media.
‒ Leave both Save check boxes deselected: The calibration will only be applied until the camera is pow-
ered off, and will not be saved.
6. 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.
7. After selecting a black shading option, a dialog box displays, reminding you to cover the sensor and insert
