Iphone Shoot Analysis

In my Iphone shoot I used the app 'Hipstamatic' to create a film-type image as the app focuses on film looking photos. I didn't like some of the photos on a number of lenses on the app I chose to use because it either distorted colour or shadow in areas that I didn't want. I liked the effect that the app uses because of the film effect, as I usually use a DSLR camera which doesn't grab this effect.
