Thanks JK, yes it was very hazy, we couldn't see the offshore wind turbines, in the last hour it cleared, but by then the battery had gone. It was very cold and very windy at first, we also had to deal with cows, I was concerned they might try to use the D800 on a tripod as a scratching post, knock it over than trample it in the mud. I anchored the camera to some barbed wire and positioned the tripod in a precarious position on the edge of a deep quarry.

I had to apply slow motion to 25% and 10% of normal to make the video which was about 22 seconds long to start with, a reasonable length. Otherwise if you blinked you missed it!

The D800 has a video trick up it's sleeve, this was the first time I have used it intentionally (don't ask!), what it does is take the exposures in a different format, then at the end of the recording it assembles a video clip, it's one single file. The finished file is quite small (64Mb) compared with the thousands of exposures I have taken in the past to assemble into a movie. It does this quite seamlessly, even when the camera's battery runs out of charge (but not if you switch the camera off before it's done). Nikon's default is five seconds per frame, one can go down to 1 second if needed to get an appropriate replay speed.
