To compensate poor lighting conditions, it is possible to adjust the Gain and DRC (Dynamic Range
Compression). The DRC works by compressing the natural dynamic range of the image, taking out the darkest
and lightest parts. This can be a particular helpful setting when the light conditions are challenging. The differences
should be clearly visible in dark parts, as they will become lighter / more grey as the DRC increases.

AAE Mode (Aperture Auto Exposure)
In this mode you can set the Iris F-stop value (aperture). The higher the F-stop value, the deeper the depth of field
you will become in the picture. The camera will automatically set the shutter speed based on the Iris F-stop set by
the user. As the camera determines the preferable shutter speed, it is possible to turn the anti flicker setting to the
required 50Hz or 60Hz to eliminate the effects of a shutter functioning at 1/50th of a second, for example. Like, with
the shutter speed in SAE mode, there is a cost. The higher the F-stop value, the more dark the picture become. To
compensate this you can set both the Gain Limit and the DRC.

Bright Mode
This mode is to try and create a decent image when the light conditions are exceptionally poor.
