RED SCARLET-X OPERATION GUIDE

955-0003_v4.0, Rev-A | 145

To calibrate the sensor the image needs to be as dark as possible:



At a minimum put a lens cap on the lens (WARNING: Not all lens-caps completely block IR. Lens caps

are made to protect the lens, not necessarily to block light.)



Preferably, take off the lens, and use the lens-mount cap provided by RED.



If possible, use a dark room.



Just closing the Iris is NOT sufficient.

Additionally a SSD needs to be inserted in the camera to store the raw images during calibration.

Calibration is required:



If the temperature deviates significantly from the currently used calibration, it is recommended to

recalibrate the sensor.



If very long exposure (~longer then 1/24 Sec) is used, it is recommended to recalibrate.

After Calibration with a lens cap on and ISO set to maximum, the sensor should show a uniform noise profile

over the whole area without any falloffs on any side. You can check at which temperature/exposure time the

currently used calibration was taken on under SETTINGS > MAINTENANCE > SYSTEM STATUS under

Calibration.

Calibration maps will still be available after performing a system restore under SETTINGS > MAINTENANCE

> RESTORE SYSTEM; however the factory calibration map will be reselected.
