While I was in D.C., I also tried experimenting with HDR on some other familiar landmarks. This is harder than you'd think, as you have to avoid the attention of the park police, who get a bit fidgety about tripods. All were shot using 6 shots bracketed at 2 stops apart, assembled and downconverted with Photoshop, with the exception of the Capitol, which was shot on a 3 shot bracket, untripoded, because the police made me put the tripod away. The camera is an EOS 20D, the wide lens is a Canon EF 10-22, the lone telephoto is a Sigma 70-200.
The success is varying. The Lincoln Memorial looks a bit wonky, but keep in mind that the sun is in the process of setting just to the right of where the frame cuts off -- this is shooting into the sun. HDR does a pretty good job of managing this!
The difference in colortone appearence between the two shots of the WWII memorial is the difference in sunset lighting over the course of 10 minutes. Light sure changes fast at sunset. Click any photo to enlarge in a new window.
