A qwik footnote: This is the compressed 30K image. The uncompressed image runs almost 250K and has better detail, especially in shadows. The fire shines out to about 3 feet away from center, fades nicely. Damned compression! Re: Gamma correction - get the test-pattern color bars and adjust for your eyes. About a third of the way over from the right, the black stripe on the lower part has 3 gradations of black. If you can discern these stripes you have a gut-calibrated display, can only be beaten by a bench-calibration.
