Those who are fans of photography and regularly use their iPhone and iPod touch to capture images will understand that great photographs come in all shapes and forms and can be captured at any location. A lot of apps on the iOS App Store concentrate on allowing users to touch-up images with effects and splashes of color, but what about those photography fans who love nothing more than the simplistic beauty and innocence of a black and white photograph? Thankfully, the App Store has a number of apps dedicated to this art, with one of the best around being the Hueless app from Curious Satellite.
