• 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.

CURRENT CALMAP

Calibration maps are stored in the camera. Due to the nature of the camera, different calibration maps

are needed for different situations.

Factory

This the calibration map generated during production. This map is always present and selected as

default on first use after performing a system restore under SETTINGS > MAINTENANCE > RESTORE

SYSTEM.

User HS

The user can select the CURRENT CALMAP. The dialog only show the calmaps stored in memory

(FACTORY and USER HS in this case).

BLACK SHADING (DEFAULT)

This option uses fixed settings which are the same used for the factory calibration (around 23 Deg C).

BLACK SHADING (CURRENT FPS/EXPOSURE SETTINGS)

This option generates a calibration with the currently set frame rate/exposure. This can be used to

generate a calibration for long exposures. After calibration (Which takes about 10 min), the new map is

automatically selected.

BLACK SHADING PROCEDURE

The calibration procedures are the same for both BLACK SHADING options.
