I dont believe it. They did an eight page spread in the Digital SLR mag on the Dave Hill effect. And they did not tell us how its done, but some really awsome images, this guy rocks as far as I am concerned.
I thought it did tell you how he does it. Multiple images composited and layered in Photoshop. There's no straightforward 'how'. Every image is different with hours of Photoshop.
HDR is better ....simple it does not alter the image except for light and colour so no manipulation needed unless you need to add something to it you forgot
Instead of full HDR simply tone map..same process same result
