Photoshop’s Gamma vs. Windows Gamma (Adobe Gamma?)

Here I’ve uploaded some screen captures and the files I used as samples

Ever since I installed Photoshop CS and Adobe Gamma I have a distinct difference in brightness between the jpeg’s opened in photoshop and ones viewed
through the Windows Picture and Fax Viewer and I believe Internet Explorer also.

Obviously this bothers me, as I am unable to create the right contrast for web-work. I can’t verify if the printing output is correct, but for now

I’m

assuming
only the webwork has this problem.

I’ll see if I can get screenshots up.

TIA,
Tiemen Rapati

How’s that?

That’s because Windows doesn’t use proper colour management. and Photoshop does.

To get things showing correctly, you need to use the correct colour space. Which means you need to learn about colour management.

Right. So the color profile of windows isn’t correct. Ironically, I have been learning about these profiles in the last couple of weeks. Well. where should I change my *incorrect* windows color profile?

Cause everything I alter in Adobe Gamma in the control panel, and whatever color profile I choose at display properties does not seem to help. I would really think setting my monitors color profile to the same one I use on those pictures in PS should do the job. But it doesn’t…

The problem cannot be ‘corrected’. Windows completely ignores the monitor profile, and Photoshop uses it correctly. The only way to make them the same is to make Photoshop as incorrect as Windows, which kind of defeats the object! Or you could use a Mac, but that way lies madness 😉

It’s a problem that has been around for a while – there’s no way to guarantee that your web images will look OK on any other (not colour managed) computer. The usual compromise is to convert the image to sRGB and get it looking right in
Photoshop, but it can still look very different on other PCs.

You can’t. Windows doesn’t use the profiles at all. Which is why it looks tight in PS (if you’ve set things up properly) but it doesn’t in anything which is Windows.

What a shame. That was exactly what I was afraid of…

Thanks
