The image settings of Facecam can be changed while Facecam is being used in other software.
For example, Facecam is being used in OBS Studio, and Camera Hub is open in Compact Mode so that settings can be adjusted.
This is especially useful when using Facecam in applications that do not offer camera controls, most often these are video conference applications such as Zoom, Slack, and Teams.
Enable Compact Mode
1) Open Camera Hub
2) At the top left, click on this icon.
3) Camera Hub is now in Compact Mode.
4) Camera Hub can now be opened while Facecam is open in a different application.
