Some sample shots showing the huge amount of dynamic range Nikon’s D800 is capable of recording. The four images were taken between 12:11 and 12:19 on June 25, 2012 in Los Angeles, CA. (I say that just so no one thinks that they were shot in the Arctic where it’s sunny all day.)
iPhone photos are posted below the D800 shots as a reference so you can see just how dark it really was. :-)
Also, here’s a 100% crop of one of the photos taken at 12:29.
