Exposure
The exposure parameter defines time during which the sensor will consume light
energy before starting to record data.
Use the Exposure slider to adjust the camera exposure time manually. The current
exposure time in milliseconds is displayed above the control. This value depends on
viewport height, decimation and sensor frequency.
If you need to set exposure even higher than the maximum slider value, use the Max
Exposure control in the Device Settings window. Check the Limit Max Exposure box,
enter new limit value and press Set.

To tune exposure automatically:
In the Device menu select the Auto Exposure command, or press E on the keyboard.
Gain
Gain can be controlled independently for Red, Green and Blue channels (R, G, B). All
gain sliders control the camera’s hardware gain amplifier. The R, G and B gain sliders
control the software gain for each color channel.
Checking the Lock Ratio check box allows controlling gain on three channels
simultaneously keeping the fixed R; G; B gain ratio.
Use the 'White balance (Hard)' menu item (Device> White Balance (Hard) or Alt+w to
balance the gain of all three channels so they are equally intense.
Note: Auto Exposure is done automatically every time White Balance (Hard) is performed.
In case of SMX-M71M monochrome camera, set gain using the All slider.
