[X] My Assistant

Sometimes when I click to enlarge an anaglyph the red/cyan colours of the thumbnail change to yellow/blue, making the normal specs unsuitable for viewing it. This happens to Stu's latest one this morning, for example, though only a minority of his anaglyphs are thus affected. It occasionally happens with other posters too, but I can't spot any systematic pattern that would suggest a cause, much less a remedy. Any suggestions?

Your computer is haunted, that's the only explanation. Give Yvette Fielding a ring, she'll sort you out.

For reference I just checked all of Stu's recent anaglyphs and I don't see any change in colour between the thumbnails and the full size image with my default browser (Chrome 4 bleeding edge developer release..). This is on a Windows 7 laptop for what its worth.

However I just checked using IE8 on the same system and what do you know I see the symptom:

This post: http://www.unmannedspaceflight.com/index.p...st&p=153158 has the problem.
While this post: http://www.unmannedspaceflight.com/index.p...st&p=153175 does not.

Both are in the Post Marquette Island thread.

The metadata in the "non buggy" jpg has the following entries "Program Name: Adobe Photoshop elements & Color Representation: sRGB" that are not present in the "buggy" version. It appears that IE8's default handling of jpg's differs from sRGB while Chrome (and MS Paint on Windows 7 for that matter) doesn't.

Interesting behavior.
Edited to add:
There's some more information on something that seems to be related in this blog post with a fairly wild example - if the bike is Green then your browser applies the embedded color profile, if it's blue it ignores it and if its red it's using the Microsoft specific WCS color profile. On my machine Chrome and IE8 display this as Blue, Safari and Firefox 3.6 display it as Green so there is some difference between this example and stu's images but I suspect it is still related.
