Got to know (not personally) Marc quite well as we both used to contribute to a photography forum. At the time he was moving from film to digital, he knew I had a 1Ds MKII, so I was able to offer some thoughts on my views on the camera (all positive).
I've always admired his work, yes, he goes to some extremes to get his images, but you still need that vision and ability to get the results he achieves. His understanding and interpretation of light is up there with the best.
