His test was not invalid at all. It simply showed how it looks like on a non-color managed browser. All this talk about screenshot color profile or the lack thereof is also beyond the point, since the top photograph was displayed correctly.
The missing screen-shot profile is not besides the point since it impacts how YOU are seeing John's screen grab. It is what is making you THINK that the top image is the "correct" one. It is absolutely pertinent to the test and the discussion.
How about instead of semantic hairsplitting (the height of which is where the emphasis in the phrase "un-tagged sRGB" is) SOMEONE posts a better test ? Show me all this theories in practice. Show me how embedded sRGB is better than an untagged one. I am not saying it isn't possible that it is, but for god's sake, just show it.
Someone, anyone!?
I did the test Slobodan, but as I said earlier my monitor is very close to sRGB so the differences are very small. I did the test with FireFox in both mode 1 and 2. Mode 2 shows differences but I have to bring the images into PS as layers and use a difference blending mode to see them. Mode 1 shows no difference, again verified with PS and the difference blend mode.
I could post the examples but they will only demonstrate that there is a difference, not which one is "right". I'm sure they won't convince you.
The best person here who could convince you is probably John, since he apparently has quite a bit of difference between his monitor profile and sRGB. All he would need to do would be to embed his monitor profile in the screen grab.
YOU can also simulate the untagged/wide-gamut scenario by doing the following:
- Get ahold of a wide-gamut monitor profile like this one:
http://www.tftcentral.co.uk/icc_profiles/eizo_sx2762w_widegamut.icc- Bring an sRGB image into Photoshop and then Assign (not Convert) the wide-gamut profile to the sRGB image.
That will simulate viewing an untagged sRGB image on a wide-gamut monitor with a browser that is using the monitor profile for untagged images (instead of assuming sRGB).
