More info from the Webcam Settings Mac App Store page:
FeaturesI gave Webcam settings a quick trial run with a Logitech C920 and was immediately impressed with a few things.
• True hardware level control of your webcam.
• View changes in Real-time to your video as you move sliders and change other settings.
• Fully plug-and-play; Webcam Settings, automatically recognizes your USB webcam when it’s connected to your Mac.
• Automatically identifies various settings that your webcam supports.
• Feel free to try any different settings as “Reset to Default” button brings back original settings from your camera.
• Works with almost every video or photo app such as Photo Booth, FaceTime, iMovie, Skype, iStopMotion, Wirecast, Sparkbooth, GoToMeeting, WebEx, Jabber, Flash based webcam app and many others.

WEBCAM SETTINGS

As noted above, there are A LOT of SETTINGS that you can control. Brightness and contrast work fine and are the two settings that I'll probably use most.
AUTO FOCUS

Having a webcam auto focus can be a problem, especially when you don't want it to. ;-) I'll be shutting off auto focus a lot.
ZOOM

Also on this panel is Zoom, which I might play with. I'm not a big fan of the zoom feature on any camera, in general, but it's something good to have in case I'm live streaming and want to get closer to the subject without moving the whole laptop closer.
Backlight compensation is a very good feature to have in case you need it.
You can get Webcam settings in the Mac App Store.
You can get the C920 on Amazon.com.
