At the same time, the titles of Bush's photographs give his images a lighter tone. On the one hand, they seem to be scientifically precise, supposedly recording the speed, direction and exact time at which the photo was taken. It's possible that he could have been diligently writing everything down while taking the photo—and I do like to imagine him scribbling these notes furiously as he struggles to keep an eye on the road in front of him. Then again, he's also introducing elements of doubt, even humor, into his titles, so I'd take these numbers with a grain of salt. These admissions of uncertainty—my favorite titles are "Beverly Hills high school students (?) cruising west at 38 mph along Sunset Boulevard on a weekend in February 1997" and "Man (possibly someone in character) traveling northwest at 60 mph on U.S. Route 101 in the vicinity of Hollywood on a late Sunday afternoon in March 1991"—make it clear that Bush isn't trying to present his images as some sort of objective truth, but instead making guesses about these people, just like you. Whether you want to see these photographs as a light-hearted take on a great American activity, or a more serious meditation on modern human behavior, "Vector Portraits" is worth a closer look.
