If you use Camera+ -- and you should; we love it -- you might have been excited by the recent talk of using the volume control buttons on the side of your iPhone to take pictures with. We've all found fumbling with the touchscreen button a little fiddly from time to time, right? I've come worryingly close to dropping my iPhone on occasions, shooting one-handed, fingers contorted into a claw, trying to curl my pinky over to the centre of the screen.
Camera+'s developers tap tap tap must feel my pain, because they recently added this much-requested feature to a new version. Unfortunately, Apple rejected it from the App Store, because repurposing the volume controls could "potentially result in user confusion." Tap tap tap is philosophical about this decision, saying they understood Apple's position and that they hoped they would change their minds in the future. Although a few other camera apps do offer the use of volume control as a shutter release, these were either only available via the jailbreak store or the developers smuggled the feature through under Apple's nose.
However, it turns out the current version of Camera+ (v1.2.1) has this feature, albeit hidden away-- but it's a snap to activate (pun intended).
