There is an overwhelming number of photography apps available. However if I were to pick one camera for beginner to advance users, it would have to be the Hipstamatic. With this camera you have different lenses and film to capture the look you hope to achieve. This is the John S lens and Float film. Currently there are 8 lens and 10 film types to choose from. Experiment and see what you can achieve!
iPhoneography classes from beginner to advance are available. Please contact me for further information. email@example.com
