Dave,
With a D2X or D200, you would set the camera up into its multiple exposure
mode. With a matte box - or even a Cokin adapter - you would have two mattes created. One would cover two thirds of the image area, leaving one third open, on one side of the viewing plane. The second would also cover two thirds of the viewng plane, but it have the open area in the centre of the viewing plane.
The camera is mounted on a tripod, and you would make the first image using (say) the matte with the open center. At this time you would have just a one third image, in the center of your sensor.
You now replace the matte with the other one, opening up one of the sides to the image plane, and make your second exposuse, using the multiple exposure feature to expose the same frame. Note that each of your exposures is a normal one, with no compensation for the multiple exposures.
You now have two thirds of the frame exposed.
Flip the matte through 180 degrees, so that the final third of the image area is now being opened up, and repeat the multiple exposure process, and you're done!
I used to do this sort of thing, in camera and on film, routinely. Once you understand the basic technique, it's dead easy and all manner of in-camera options open themselves up to you.
Thanks for all the comments everyone. I quite like this photo.
As do I.
