These were shot with an Olympus E-1, 50mm macro, I believe at F2 with a shutter speed of ~1/125 and around 400 ISO. I will have to go check the exif. Smugmug doesn't seem to allow it on hosted pictures, though, it is at the site.
I did use a tripod and shot in Raw. I adjusted the white balance in CS2 to match the light temperature(20k) to get the colors natural. Resized and sharpened.
