Adjusting camera settings on a Mac is primarily done through the specific applications that utilize the camera, such as FaceTime, Zoom, or Photo Booth. Each application has its own settings menu where you’ll find options to adjust video quality and brightness, as well as select which camera to use if multiple cameras are available. Open the application, navigate to its settings or preferences, and explore the camera section.
Additionally, you can also check System Preferences to regulate privacy settings. By going to System Preferences > Security & Privacy > Privacy > Camera, you can manage which applications have access to your camera. Ensuring the applications you want to use have the necessary permissions is essential for optimal camera performance on your Mac.
