Difference Colors Gimp / Firefox

Hello,

All my images are using the colour space Adobe RGB 1998.
I work my images with Gimp, I did a fresh reinstall of Windows 7 last week and since then I can't get the same result on Firefox or Chrome of the images I upload. I loose colours. When I open the image with Gimp colours are fine.

So I would like to know if it's my installation of Windows 7 which prevents me from seeing the Adobe RGB 1998 colours or if Gimp does not save correctly the images.

How to check if Windows 7 and Firefox or Chrome can display Adobe RGB 1998 images ?

I attached a file to the left what I see with Gimp, to the right what I see with the image opened with Firefox or Chrome.

Thanks,
Vincent.

A couple of questions: Are you working on a laptop or a desktop? And is your monitor calibrated? If you are using Firefox or Chrome, your browser is already color managed. Having said that, it is best to save your images in the sRGB color space for viewing on the web, because you never know what your potential customers/buyers are viewing your images on. I don't know about Windows, but on a Mac, the inbuilt monitor calibration tool works very well. Not sure if Windows has this monitor calibration feature.

It's a SONY Vaio laptop, this one : http://www.sony.co.uk/support/en/product/SVS1311C5E to be more specific.

If I reinstalled Windows 7 it's because I changed my disk to a SSD one.

I am going to put back my old hard disk, to see if I can get the right colours. I let you know.

Regards,
Vincent.

Ok, I am using the old hard disk and the colours are the same on Firefox and on Gimp. So the problem comes from my new installation of Windows 7 on the SSD disk.

Does anyone know what I should do on this new installation or what I could recover from the last installation ?

I shoot Adobe but convert to sgrb for the web.
Even if the browser does a good job you never know how a monitor of your customer handles Adobe RGB. I would trust Gimp. Besides that you always have your RAW image that you can supply in Adobe RGB when needed.

Sounds to me like you might have had your monitor calibrated when you were using your old disk or had some sort of a custom profile, which is now missing on your new installation of Windows. To check if you had a custom profile installed on your old hard disk, go to Control Panel -> Display -> Screen Resolution. In here you will find the "Advanced Settings". Click on that and then navigate to the "Color Management" tab. Once there, you will find "Color Management" tab in the middle of your screen, click that and once it opens up the dialog box, check to see if there are any profiles there. If yes, then you'd have to copy that color profile, which probably will be located in the following directory C:Windows -> system32 -> drivers -> color, to your new SSD and see if that helps. A better idea might be to copy the entire contents of the "color" directory and put them in the same location (C:Windows -> system32 -> drivers -> color) on your new SSD. Having said all that, here's my disclaimer, you will be trying this at your own risk :). I am NOT a Windows expert and my knowledge is limited.

Most laptop monitors do not calibrate all that well.

You need a really good Dell or Asus graphics monitor.

You also need to check the brightness level All colors are thrown off by screens being far too bright.

Your brightness level should be around 80 cd/mm*2. It is probably around 300 now.

You want the brightness of a reflected light hard copy of something to be scanned into the machine,
to match the screen brightness which is projected light a mismatch unless brought down to 80 cd/mm*2.
And then that should match the reflected light of a newly printed copy.

Projected v Reflected light matters greatly.Control over most laptop monitors for brightness is wonky at best.
