(4) Setting the camera gain
When the exposure mode is Manual, you can adjust the exposure arbitrarily by setting the shutter speed and camera gain
(sensitivity). The camera gain is used to set the sensitivity of the image pickup device. When a higher value is set for the
camera gain, darker objects can be captured. However, higher sensitivity is likely to cause more noises in the image.
How to adjust the exposure
DS-L3 determines the exposure by the combination of exposure time and camera gain.
1 Display the [CAM MENU: CAMERA] long screen.
2 Confirm that the exposure mode is set to manual.
Confirm that [MANU] (manual exposure) is shown on the
[EXP MODE] button.
Note: When it is [PROG] (program AE), [S.AE]
(shutter-priority), or [F.AE] (focus-priority), the [CAM
GAIN] button is shown as the [EXP CMP] button.
3 Press the [CAM GAIN] button of [CAM MENU].
The [CAMERA GAIN] submenu appears.
4 Use the button and slider of the [CAMERA GAIN]
submenu to adjust the camera gain value.
The camera gain setting is common among different DS
camera heads and is as follows:
•
Setting range
100, 120, 140, 170, 200, 240, 280, 340, 400, 480, 560,
680, 800, 960, 1130, 1360, 1600, 1920, 2250, 2700,
3200, 3840, and 4600 (23 levels)
Adjust it viewing the live image.
