what am I doing wrong?

I open a TIFF sRGB image in Photoshop 6, assign the Adobe 1998 profile, do my colour corrections, convert into sRGB and save it as jpg with the sRGB profile attached. When I look at it using Internet Explorer the colour appears shifted. If I open in Photoshop, it looks just fine. I'm totally confused. Doesn't IE display images as sRGB ?

The sRGB colour profile isn,t as wide as RGB The colour range is narrower
The sRGB is more suitable for web images

When you assign Adobe 1998 to your image that profile has a wider range than sRGB, hense the more dynamic colors. When you display on the web using Adobe 1998 as the embeded profile some of the color range is 'cliped'. This is a very brief non- tech answer, for more detail do a search.

For web work/display you are beter off to assign the sRGB from the start or convert when finished your corrections but before sharpening and boost the saturation/curves etc. Then sharpen and save for web.

Herbert, I think the problem is that you ASSIGN to Adobe 1998. That gives a color change. You can notice that the colors look different. What you should do is CONVERT to Adobe 1998 and do your corrections. Or you could stay in sRGB all the way.

I'm converting to sRGB before saving and saving with the profile attached.
but IE still shows the colours differently.

I will try again....when you assign Adobe 1998 ANY corrections you apply are made using the wider color range of a/1998. When you convert back to sRGB the Adobe colors are CLIPPED and you see a color shift when viewed on the web.....Solution/??/

Boost the saturation or curves or what ever you use after you convert back to sRGB or STAY in sRGB and dont use the Adobe 1998 workspace...

That process seems to work for me (just tried it). Is your original TIFF image already in Adobe 1998 but untagged? If not why are you assigning this profile? All it does is interpret your pixel values as Adobe 1998 "pixels" and if that is not how they were generated then it doesn't seem to make sense to me to do this assignment (but then again I'm no expert in color management).

In any case once you do the Convert to sRGB and save with this profile attached then Photoshop and any browser should both see it as an sRGB file and they should both display the same colors. That is if you have your Working RGB set to sRGB. If you have that set to Adobe 1998 then you may see the shift depending on your selection on the prompt that pops up when you open the sRGB image (for instance if you select Don't Color Manage).

However he says he converts to sRGB in Photoshop and then saves as JPEG with sRGB profile attached. Any "clipping" should occur when this conversion is done. Whether the new file (which is now sRGB and knows nothing about ever having come from another colorspace) is later opened in Photoshop or in a browser should not make a difference.

Also I just tried the workflow he mentioned and I don't see any shifting of colors between PS and browser when viewing the sRGB jpg. I am questioning the procedure of Assigning Adobe 1998 in the first place but there may be a good reason for that (some cameras can record Adobe 1998 but fail to properly tag the file with this profile).

He said the file was in Tiff/sRGB - he assigns Adobe 1989 and applys color corrections, then converts back sRGB. The clipping happens there.

Go to IMAGE/MODE/ASSIGN and use the pre-view button when you assign back to sRGB and you CAN see a color shift.

Further if you only assign the ICC the file will not retain the profile unless you SAVE for web...or Save with the ICC.

Adobe 1998 is a wider color space than sRGB ..it will clip when converted back.

but wonder if it's a question of "display using monitor compensation"? - I have this set to 'on' in PS but IE, and certainly Windows 'Picture & Fax Viewer'. seem unaware of my Adobe gamma settings... so I get an appearance shift too....
Sorry if way off the mark, john

Exactly, the clipping happens there. Which is why it from that point on it shouldn't matter if he looks at this file in a browser or in PS.

I think we agree on what happens but I think you have misread his problem (or maybe I have

. He's saying that the generated sRGB jpg file looks different when opened in PS and a browser. That doesn't make sense.

That could be a good explanation. In PS7 I believe it is called ("Blend RGB colors using Gamma") but it's probably the same thing.

But then that would happen for each and every sRGB image he opened. I.e. it would look different in PS and a browser no matter what.

Since you already started with an sRGB file and you are putting it on the web. Don't assign Adobe 1998. The easy for you is to set PS6 working space to sRGB, open the sRGB file, do your corrections, etc. save file preserving the sRGB profile and then upload the image to the web.

If the use of image is for web its no point assigning Adobe rgb & then doing correction, Let the image remain in sRGB & save for web, the image will remain in srgb by default & should show the same in IE & PS as long as you keep your working space Srgb in PS6, If your working space is something else ie: adobe RGB & you have assigned a function " what to do if profile mismatch" & you assigned "convert to working space" which in your case the image is Srgb but before opening in PS , the image gets converted to your working space.
This is what will cause color shift when you see the image in PS6 / IE.

well fellows, sorry for taking long to answer. I rebooted my PC this afternoon, which I usually leave on the whole time, and everything is back working as it should. Boy I hate Microsoft.

At least it served me to know I don't have to assign Adobe 98 profile to my sRGB image in order to colour correct. By the way I was testing that iCorrect software and so far, I'm really impressed. it fixes skin tones quite quickly. Anyone using it?
thanks to all of you that answered so promptly.
