The day I got my DSLR, many years ago, I took a bunch of test shots having no clue what I was doing. One of those shots I have always considered my best photo, ever, even though it was totally random and lucky. As of yesterday, that shot has been replaced as my favorite shot ever, with an image I took with my iPhone 4S.
