It would be hard for me to point to a single spot on campus and claim it as my favorite to photograph. Were I compelled to, however, I think this vantage point on the Social Sciences Quadrangle would be my choice. This linked image is perhaps the most striking I've ever made from this spot. It appeared on Roger Ebert's blog and on the Social Sciences Department's Holiday card; compliments I find flattering even to this day.
I made that blue photograph in early 2010, the months before I left campus for Stanford and a winter that saw significant snowfalls. I have found myself back again, but perhaps never to greater effect than my most recent trip during the snow storm that dumped six inches in the span of a few hours (and left me with a two hour commute home from the south side).
There is a delightful contrast between the blue image and this one and it illustrates so neatly the myriad ways in which photographs can be striking with or without a does of heavy processing. The lead image on this page benefits from its hyper-realistic nature: it's enormously detailed and captures so completely the primary visual experience of standing in the snow looking at the stone facade (see the detailed crops below). The linked image makes up for its lack of realism with a heavy dose of color and contrast to convey the chill of the air.
