How can I change my webcam settings?

I'm using a Microsoft Lifecam Studio webcam with my mac Mini and Skype. The camera is detected and I can make and receive video calls.

However, I cannot control the camera settings. On Windows I had an application for the camera so I could set the colours, brightness, etc. However, I cannot find the same app on the mac. So, is there a way that I can adjust my webcam settings (for Skype)?

[SOLVED] Replying to my own post, purchased the "Webcam Settings" application and that fixed the issue.
