I hope I'm not muddying the issue (or doing something stupid at my end), but
your posted Cornell .png photograph is definitely the worst of the lot, when
viewed on-line in the latest Firefox browser (v3.6.13): low contrast and darker
than any of the POV-Ray images. Perhaps it needs tweaking in some further way,
to make it a good comparison image? (I'm *guessing* that it was meant to compare
more favorably with the gamma 1.0 image, or vice versa.) Here are some simple
screen shots, assembled in Photoshop (which didn't materially affect how they
appear in Firefox); just a simple JPEG.
