One does not wait in the hot humid weather and fight the crowd to get a good view of the Mona Lisa or study the brush strokes of Leonardo de Venci. All this effort is to simply snap an phone picture of it, or worse, a ‘selfie’… It is behind glass, so all photos have glare and reflections of other phone photographers. The end result is a snapshot of very poor quality. If you really want to see it, you would go to an art book. There is no organization, like a clockwise flow, entrance and exit. You have to struggle just as hard to get out of the mosh pit as to get in! I think a LOT of travel is just so one can say, “I have been there….”
The iPhone is a little irritating to a serious photographer. The iPhone takes some wonderful photos in a much easier manner than carrying around a large DSLR camera with interchangeable lenses. Now days, most photos do not go past the sharing on the Internet phase, so the resolution and ability to enlarge and print does not come into play. It also helps prove the best camera is the one you have with you, and the iPhone or any such Smart Phone camera is certainly always by our side.
