The colors of Yellowstone Canyon edit

Original - Grand Canyon and Yellowstone Fall at Yellowstone National Park.The canyon is up to 900 feet deep (275 m) and a half mile (0.8 km) in width.The canyon below the Lower Yellowstone Falls was at one time the site of a geyser basin that was the result of rhyolite lava flows, extensive faulting, and heat beneath the surface (related to the hot spot). The rhyolite in the canyon contains a variety of different iron compounds. Exposure to the elements caused the rocks to change colors. The rocks are, in effect, oxidizing; the canyon is rusting. The colors indicate the presence or absence of water in the individual iron compounds. Most of the yellows in the canyon are the result of iron present in the rock rather than sulfur.

Comment - what is up with the colours ? At first glance the picture appears over saturated and has far too much Yellow. The water and snow(?) have obvious yellow tints. Compared to this the colours look unnatural. I like the resolution, angle, sharpness and even the rocks in the foreground - Peripitus (Talk) 23:52, 16 July 2008 (UTC)[reply]
Thank you for the comment. I tried to correct the water. What do you think? The image you reffer to is way to dull. Compare to this and to national geographic image please.The colors of the rocks deppend on time of the day and time of the year the image was taken. Maybe part of the water color problem was that there still was more than enough melting snow to affect the colors of the waters, but the rocks are really yellow in the real life, when they are lit by the sun.--Mbz1 (talk) 00:17, 17 July 2008 (UTC)[reply]
Weak oppose, but want to support if we can settle on a good edit. I agree the colors look over-saturated, which seems improved in the edit, except the edit seems to have introduced artifacts in the sky -- the hazard of saving and resaving JPEGs, I guess (see for instance the blue gap in the clouds top center, which looks much nicer in the orig).

comment I do not see artifact at the sky, but please let me know, if somebody has a wish and a time to edit the original image. THanks.--Mbz1 (talk) 03:24, 17 July 2008 (UTC)[reply]
