Not sure what I think about this. Truly a digitally enabled phenomenon--who would develop all of those pictures, and where would they have collected them, otherwise? But so many other considerations here--like, is this rude to surrounding diners? Is this a great way to help control your food intake? Is it just a nice hobby? I write all this as someone who has, at intervals, photographed particular dishes, and particular cocktails, if not particular servings.
