Zoom In or Out on a Subject with the PlayBook Camera

The BlackBerry PlayBook camera includes a digital zoom that allows you to make a person or object appear three to four times closer. The camera will always start with a wide angle view, which is often quite acceptable for a snapshot.

To zoom in closer, tap anywhere on the screen image (except on the virtual shutter release) to display the controls. Move the slide up toward the + sign to zoom in, or back toward the symbol to zoom out. Make your adjustments in small increments; the screen view will lag slightly behind your changes.

The zoom digitally enlarges the image, which is less sharp than using an adjustable optical lens.

The zoom on the PlayBook camera — like those on other tablets and on nearly all smartphones and many simple point-and-shoot cameras — is a digital zoom and not an optical zoom.

An optical zoom uses an adjustable optical lens to enlarge or widen the image that comes in to the sensor. A digital zoom works with a non-adjustable lens but instead uses the computer processor to enlarge a portion of the image to make it appear closer. An optical zoom delivers a better quality picture, but if you think about it, where in the world would they stick an adjustable lens in a thin tablet or smartphone?
