The problem: The camera flash on your mobile device, while good enough for lighting up quick candids, is mounted on the device itself, right next to the shutter. This inevitably washes out your photos and renders skin tones leprotic and wan. There's no way around it -- unless you move the flash off-camera. But this presents a new problem: No one wants to carry around a separate flash unless you're a hardcore photography enthusiast. That's the one-two problem combo developers Joe Walnes and Alex Lukashevich aim ed to combat in developing Nova.
