STICKY:  Color problems? [work in progress?]

If you shoot Raw, the color space is set in the Raw converter. In camera settings don't matter (only affects the preview and histogram)...

And filename. Adobe RGB images will use _MG_2492.CR2 while sRGB images use IMG_2492.CR2.

I'm with you for everything except the ICC profile. How do I embed it & where do I find it? (CS3).

Thanks for the great explanation!

If you save or 'save as' in PS, there is a tick box "Embed Color Profile"

Thanks! I feel stupid--I thought the ICC profile was different than the colour space.

Lots of people over-complicate color management. There is a lot of misinformation about it, and I've stood my ground since it first reared its ugly head. sRGB is essentially what you see on screen. It is what most devices will expect. It will rarely lead to surprises.

As the first post says, it may be a good choice for beginners.

I think it may also be a good choice for professionals.

Learn to make the most of your images and optimize corrections. Calibrate your monitor. Work in sRGB and be happy.

You can definitely get other color spaces to work...I have seen very few good images where it makes much difference.

Sounds like we agree :
Use whatever color space that gives best results

Hey colour guru's!

I'm having an awful time trying to get my head around all this, there really is too much info! I'm wondering if somebody can help me out?

Take a look at the screenshots below....

Take a look at the screenshots below....

On the left is Safari, and the image how it looks in photoshop and my other apps I use on my mac. On the right is firefox, urgh!!

Below is a screenshot of my colour profile in CS3 (I haven't touched this).

And below is the image, set as my wallpaper (as it looks in CS3) also showing my iMacs calibration...

Which is correct? Obviously the one on the left looks better, but is that right?

While your settings are set to sRGB (in PS) the image in question is likely not. Can you post the image itself? I bet it is Adobe RGB. Or simply check for yourself by choosing Edit > Convert to Profile (what does it say the current profile is?). Click cancel.

Safari is a color managed application so it reads the profile and displays the "correct" output. Firefox is not so it assumes the image is sRGB and displays the image "incorrectly".

Also, if you calibrated your screen did you create a profile, maybe iMAC calibrated? If so why are you not using that and using the sRGB? Have you read this thread?

I relaise that Safari is colour managed and Firefox is not, however presumed that all would be OK as I thought the image was saved as sRGB. The profile iMac calibrated is standard for the iMacs, I usually use this but for this explanation I changed it so all colour setting were the same.

I'll check the edit>convert to profile when I get home and let you know how I get on. The image is here...

The image looks just like your FIREFOX screen shot above in IE. Opanda IEXIF shows "uncalibrated" for the color space. This means that the color space is either a) NOT embedded, or b) NOT sRGB. Convert the image to sRGB using Edit > Convert to Profile should solve your web color problems.

You my firend, are an absolute star!!

I'll have a bash when I get home, cheers!

check you arent assigning a profile, convert then save instead...if it looks ok before you save after the conversion it should look ok in firefox.

I've read so much on this subject and while updating my ATI video driver did make my problem better, it is still not completely resolved. Or perhaps I am expecting too much?

My Acer Aspire laptop monitor has been calibrated with a Spyder2Express and the resulting profile is the default profile for the monitor.

My PS color settings are:

in an unmanaged app, its displaying using your monitor profile...in PS its displaying it using the sRGB profile. The difference your seeing is just that, the difference between your monitor space and sRGB...the two will always have some difference.

A word of warning, working in monitor RGB is not a good idea...but for a test, convert your sRGB to monitor RGB then save that out and look again, the two should now be indentical. Dont however use this to give to someone else, because they will have a different monitor RGB and consequently it will look different again on their monitor. This is why device independent profiles such as Adobe RGB or sRGB (or the other ones in that bracket in PS's colour prefs) are used, so that CM savvy apps have a common ground to look to.

Again, working in monitor RGB is really a no-no...its only when you fully understand why you shouldn't that you will then know under what limited circumstances you can
