Webcam on teams is dark and cannot change settings
Using a Microsoft Lifecam on Windows 10 with Teams is a no go, the image is extremely dark and there is no way to change any camera related setting. meanwhile on Skype and other video apps, the camera brightness and other settings are automatically adjusted and it all works fine. Skype also allows the settings to be manually changed.
As it is, Using a Microsoft Lifecam on Teams is impossible

Sometimes it's too dark, sometimes not. I have sufficient forward and downward lighting. I can't figure out the pattern for when it's "too dark" to be usable. Restarting Teams helps sometimes.
