After a software update earlier this year, Google Glass became more photog-friendly than ever. The camera now includes a built-in HDR (high dynamic range) feature that boosts its ability to capture good shots in mixed light or strong background light, which helps Glass's built-in glass a lot.
With an ultra-wide lens, Glass is designed to capture everything in a human's natural field of view. It actually takes a bit of getting used to, but the device boasts a great wide angle for landscapes and nature photography. No lugging massive lenses up a mountain necessary.
