I had the white balance set to Sunny. With the D700 set to Auto, I got a bluish tint in some images I shot last year in Amman so I quit using Auto. The camera is everything people say it is- incredibly detailed RAW images. Despite its size, it handles well. I'm really looking forward to getting the camera underwater; macro images with it and the new 105VR are going to be stunning. It's a card hog though, RAW images at 14 bit color depth are over 30 megabytes.
I'll be in Lashkar Gah for a week beginning tomorrow and will take the D3x. We are setting up an office down there so I don't expect to come up with anything interesting but it's a chance to become more familiar with the camera.
As to the children- I think they were a bit intimidated by the blonde lady! There is a lot of sadness here but the children don't seem to be too affected by it. They laugh a lot and are indefatiguable at play.
