CamWiz Webcam Recorder 1.0

CamWiz Webcam Recorder lets you take total control of webcams on your mac. You can use it to view, record and play back webcam video.

The app has a built-in tuner module that lets you adjust the source video quality such as contrast and brightness. You can then use the tuner output as a virtual webcam with any other apps on the computer such as Skype. This function is particularly useful when your webcam is too dark or too bright for your settings, since most apps on mac do not have ways to adjust webcam settings.
