By far the found object that I have photographed the most is coffee cups.  Thousands of photographs of hundreds of cups.  You think there are just a handful of styles until you start flipping through the files and see the large variety.  Some of the cups are left in ways that look completely staged.  I don't touch them at all - I simply document what I see, trying to capture the beauty and wonder at the story of how the object ended up where I found it.
