It's not uncommon for photographers to feel much more at ease behind the camera rather than in front of it. Duo, a concept from Chin-Wei Liao, a Korean design school graduate, aims to transform the person behind the lens into photographer and subject simultaneously. Each half of the Duo is an individual camera. Assembled as one unit, pressing the shutter will record an image while capturing a picture of the person using the camera.  

The Duo concept camera consists of two imaging modules. They can operate together or as separate imaging units, each able to remotely trigger the others' shutter.

The most obvious application is the 'selfie,' the quick self portraits popularized by the rise of front-facing smartphone cameras and apps like Instagram. More interesting is the Duo's capability to function as two independent-but-still-linked cameras when split into its two units. Each contains its own shutter button, lens and LCD; firing the shutter on one camera remotely triggers the other, capturing two images at once. Both images are saved side-by-side as the final product.

Designer Chin-Wei Liao created the Duo concept as a graduate project at the Royal College of Art, in London. For now, it's just a prototype still tethered together by wires, but it's an interesting idea. Let us know what you think in the comments.
