Technology: Time for a new app? Instagram has sold out to Facebook, but Snapseed (£2.99) still offers lo-fi filters in an easy-to-use package. TiltShift Generator (69p) is true to its hipster roots by making big things appear small. Why not ditch stills entirely and upgrade to video with Viddy (Free). Dramatic Black & White (69p) reproduces the traditional black and white darkroom look with this simple app. Disposable Hipstamatic (free) blends lo-fi filters with the throw-away fun of a disposable camera.
