: and the one I remember:

Chromaticity is almost identical between those shots on like-for-like diffuse elements. Lumma contrast is a bit higher in shadow's image, although that doesn't necessarily mean much; capture settings can play hell on contrast. Also, Halo 1 usually looks washed out in the lumma when viewed on an LCD.

At any rate, that's a terrible capture you posted. Very blurry with some upscaling. The original game looks much better. :P
