The Galaxy Tab 10.1's front-facing camera is sufficient for video conferencing, but it really demands decent lighting to avoid streaming grainy video. Poorly-lit environments aren't much of a problem for the rear-facing camera, but quality still falls shy of what we're able to achieve with Motorola's Xoom and Acer's Iconia A500.
Enabling the flash yields better shots, but the light seems poorly distributed in close-up pictures (more so than other tablets that have passed through out SoCal lab, at least).
Outdoors and in full sunlight, the Galaxy Tab 10.1 performs as well as any other point-and-shoot camera. The biggest problem is that Samsung omits a zoom function, which forces you to crop your own pictures after they've been shot.
