Soft Proofing not working for sRGB

I have a new iMac 27" running the latest Photoshop with macOS Big Sur. When I try to soft proof in sRGB with a file that has an embedded sRGB profile the image shifts to a very saturated red. I checked my old mac pro and this is not a problem on that machine. After a bit of troubleshooting I discovered if I go to Color Settings and change the Conversion Options> Engine> from Adobe (ACE) to Apple CMM, the softproof does not shift and seems and looks correct to me. 

 

From my experience I don't want to change the Conversion Options to Apple CMM but perhaps someone can tell me if they have another way to fix the problem. I would greatly appreciate it. I cannot find this exact problem I am having in any threads. Thank you. 

 

The image on the left shows the sRGB embedded profile without soft proof and the one on the right is in SRGB soft proof with Adobe (ACE) conversion engine.

Correct answer TheDigitalDog

If you have an Adobe RGB (1998) document and you soft proof to sRGB, OR you convert to sRGB, the results should visually be the same. That they are not is apparently the issue. 

You might see if this is an issue with the GPU. First, try disabling GPU in the preferences (Preformance tab). Any better?
If not, recalibrate and build a new ICC display profile, the old one might be corrupted.
If you are using software/hardware for this task, be sure the software is set to build a matrix not LUT profile, Version 2 not Version 4 profile.
If turning OFF GPU works, it's a GPU bug and you need to contact the manufacturer or find out if there's an updated driver for it.

Hi

There is no reason to softproof an sRGB file to sRGB. It should be identical in with and without.

Can you please tell what it is you are hoping to do here - also paste a screenshot of the view/ softproof/ custom dialog window into your reply here. [please don't attach - there's an add photo button in the toolbar, next to the filmclip]

 

Are you sure that the two sRGB profiles are the same (the embedded one in the file and the one you're selecting as softproof) 

There are a LOT of sRGB profiles floating around out out there. Make sure the naming is identical. 

The two CMMs could see profile differeneces differently (but I'd be surprised if they did) 

 

I hope this helps

    I understand there is no reason to softproof to sRGB but if I have an Adobe RGB color profile instead and try to softproof to sRGB in the Photoshop settings which seem to be what Photoshop is providing, the color is really off as well. It seems the only work around is to not softproof in sRGB and convert the file to sRGB and believe that is correct versus the softproof. The sRGB profiles are the same. This does not happen on my older computer. 

     

    I thought I was posting this to Adobe support. If you could send me the link to that help forum I would appreciate it. Thanks.

    Is this on the iMac screen, or do you have an external monitor attached? There is a current issue with iMacs/MBPs + eternal monitor where the wrong monitor profile is used in certain situations. This could be one such situation.

     

    You should probably post this on the feedback forum, which is the official bug report channel, monitred by Adobe engineering staff. Include as many system details as possible.

     

    Can you post an actual screenshot, not a photograph? Embed your display profile and don't convert to sRGB to avoid clipping the data.

      I do have an external monitor but it happens when the monitor is not attached as well. I will post on the feedback forum. 

       

      Here is the screenshot. Image on the right is softproof with sRGB in Adobe (ACE)
