There are tons of applications for editing photos taken after they have taken :
Instagram , Hipstamatic and luminance to name a few. But why not they fit before? That's exactly what photojojo proposes with its series of interchangeable lenses for the iPhone developed specifically to do . Easy to install ( you have to adjust the lens to slide on the camera ) ,
you can can achieve three effects : fish eye , macro or telephoto . Each lens is sold separately , but a pack of 3 for $ 49 on the official website. The company has a number of other accessories too, but that is by far the greatest success .
