Mountains and Clouds revisited
In my last blog entry, I posted a photo of Alexander Calder's Mountains and Clouds sculpture, which is located in the atrium of the Hart Senate Office Building. I shot the photo with a new ultra wide-angle lens that I had purchased, viz. the Nikon 12-24mm. Since then, I exchanged that lens for the newer Nikon 10-24mm ultra wide-angle lens and revisited the atrium to take another shot of the sculpture.
I think this version turned out nicely. If you compare it with the previous version, which I took with the Nikon 12-24, one of the first things that you may notice is that there's less of a problem with parallax or keystoning. This is because the Nikon 10-24 is noticeably wider and I was able to point my camera perfectly level with the ground and achieve the same composition. With the previous photo, I had to point the lens slightly towards the ground in order to capture the front-most potted tree. While the two lenses have only a 2mm difference in minimum focal lengths, the difference in angle of view afforded by 12mm (99°) and 10mm (109°) is quite dramatic in practice.
