A blank image appears in the Photo Booth window
If your digital video camera is turned off when you open Photo Booth, you will see a blank image in the window.
If you turn off the camera with Photo Booth open, the image freezes. You can still take a photo of this image.
Make sure your digital video camera is turned on. For more information, see the instructions that came with your camera.
To turn on an iSight camera, turn the front edge of the camera clockwise. A green light indicates that the camera is on.
