d and I went to go see the Michael Wolf "Architecture of Density" exhibit over at the Robert Koch gallery in downtown SF (at the intersection of Geary and Market). The online gallery had more photos than the actual exhibition, but there was a lot to be gained from seeing the photos in person. So many of the building details are not evident in the small images on Wolf's Web site: workers hanging precariuosly from the scaffolding, plumbing fixtures climbing up the stories, the lack of people in the photographs (altering the voyeuristic quality of the photos somewhat). Also hard to replicate is the sense of light-headedness I got from seeing the photos blown up to gigantic proportions -- somewhat like the feeling one gets looking down from the top of a tall building. d noted that the photos were grainy and clearly digital, which might make it difficult to stomach the $4-6K price tag, though the light-headed feeling would be enough to keep the photos off of my wall.

There are more photos in the online gallery, but these are some of the ones (IIRC) that are in the actual exhibit:

Update: d points out the work of Andreas Gursky as well: * Singapore Stock Exchange * Gallery with some of his building facade photos * MOMA exhibit * Google Images search has even more works
