If you have a digital camera and you want a larger screen to view your subject matter instead of the small LCD view finder on the back of the camera, you can connect it to your computer. Once connected to your computer you can see everything your camera lens sees, except in a much larger scale. This allows you to easily notice everything that is in your shot.
Plug the USB cable into the USB port on your video or still camera, then connect the other end of the cable into any available USB port on the computer. Power on the camera and set it to the record mode.
Launch the video-editing software you have on the computer. Although most computers come with a preinstalled software title you can use other store-bought programs.
Click the "Capture" option on the video editor. A window appears, asking what you want to capture from. Select the connected camera. In a moment a screen appears and displays everything the camera sees.
Take a picture with your still camera or press the "Record" button on the video camera. While the camera is recording its data you can see the content on the computer screen.
