I was going to send this as a message to Rocky as he just got a D7100 as well but thought that this would be great to share with everyone that hasn't explored the white balance settings of "K"elvin.
When shooting a sunset or rise it never seems to match as well as I would like. By adjusting the Kelvin setting you can really dial it in. To access the Kelvin setting you hold down the WB button on the back of the camera and rotate through the various white balance settings until you reach "K". Then use the front dial to raise or lower the Kelvin number. Higher the number gets into the blue light spectrum. Lower number goes into the yellow.
If you haven't played with this you gotta give it a try!
