The WPILib Camera VIs were originally written for the Axis VAPIX API. When USB cameras were added, they were added via the NI IMAQdx libraries. About half of the properties return a "not supported" error, but some others were extended to have a custom setting.

Lately, I've been using the Vision Acquisition express block configuration. It leads through five wizard screens with a test mode to view the changes as you experiment. It then generates code for IMAQdx. Once done, I will generally right-click and Open the Front Panel which will convert it to a VI. This gives a good starting point for more advanced configuration.

To darken, you can make adjustments to exposure, gain, and brightness.
