I absolutely love my mirror-less and DSLR cameras but I also love taking photos with my iPhone 6 Plus. Its camera only sports an 8MP sensor but it definitely packs a big punch. I also always carry around with a Sony RX100 M3 camera that has a 20mp sensor but I still find myself gravitating towards using the iPhone more. One if the reasons for this is the plethora of photo editing and processing apps that are available. Among these is an app called Hipstamatic(direct link.)
Hipstamatic is a really nice app that gives the look and feel of using a real camera. What also makes this app stand out from the others is the ability to select from various film and lens combinations. My favorite combination is the John S lens with AO DLX film. I have found this to be the perfect combination for street photography. I have been using this app more and more as of recent. Some of my recent shots are below.
