(3) Setting the camera gain
In [M] (manual) exposure mode, you can set the desired exposure by adjusting the shutter speed and camera gain
(sensitivity).
The camera gain sets the sensitivity of the image pickup device. The higher the value you set for camera gain, the darker
the objects that can be captured. However, higher sensitivity is likely to cause more noises in the image.
How to adjust the exposure
In the DS-L4, the exposure is determined by the combination of exposure time and camera gain.
1 In the LIVE menu, make sure that the exposure mode is
[M] (manual).
2 Tap [CAM GAIN].
3 Adjust the value of the camera gain.
The following shows the range of values that can be set as
the camera gain:
 Range of values that can be set
100, 120, 140, 170, 200, 240, 280, 340, 400, 480, 560,
680, 800, 960, 1130, 1360, 1600, 1920, 2250, 2700,
3200, 3840, 4600, 5520, and 6400 (25 steps)
Set the desired value, viewing the live image.
4 Tap [OK].
Settings at the power-on time
The camera gain setting is saved when the power is turned off, and restored the next time the power is turned on.
However, if a custom setting is selected ([SETTINGS] > [DS SETUP] > [MAIN] > [CUSTOM No.]), the camera
gain value specified in that custom setting is used.
