I never thought to look at the Olympus Forum on DPR. My bad.
The images are indeed a series of captures that are turned into Photoshop layers.
I'm done with this series, although I recently started to look at some raw files that I never composited from it. I worked at Nighthawks and Staccato for about 6 years, and during that time I exhausted my creativity envelope. It was clear that I could get many more good images with more time on target, but I'd stopped growing with the series, and therefore it wasn't fun any more.
I'll be back here.
