As I have been teaching photography for years and just got into iPhoneography recently, I had to be a bit more serious and study the subject deeply.
For 5 months I ran all my photography workshops with my 5DIII and the Sigma 35mm lens, along with my iPhone. When an interesting situation happened, I took 2 photos of it: one with the DSLR, and the other with the Phone. This article shows the results, and dicuss the pros and cons of iPhoneography.
