P: Images opened in Photoshop appear far brighter than they are.

Hi all, we hope to have a fix in an upcoming build next week.  Please make sure to check your version and update whenever there is a new one.

Thank you for your patience.

Thanks,

Cory - Photoshop Product Manager

At least with me, it appears to be a temporary issue because toggling **off** what CShubert suggested **did** fix the issue upon restarting Photoshop Beta. But on a whim, I toggled everything back **on** (Performance > Use Graphics Processor **and** Technology Previews > Precise Color Management)…restarted the app…low and behold everything was back to normal; the colors are perfect again.

Still exists in the latest 27.10 on Tahoe Version 26.5.2

I reported the same problem yesterday. I had to downgrade to 27.8. cheers!

Hi all, the team is aware of this and working on a fix.  The workaround for now is to go to Preference/and either checking or unchecking Precise Color Management for HDR display, turning off Use graphic processor or turning off Preference/Technology Previews/ Precise Color Management.

Here is another thread talking about the same issue:

Im having the exact same issue with version 27.9.0! Im on Sequoia.

Yes, I’m having the same issue with Photoshop Beta 27.9, and yes, if I open the image in Photoshop 27.8, it appears fine. 

I have opened the same files in Photoshop 27.8.0 and the previous version of Photoshop Beta 27.8.0 and the image is fine. So I think we can conclude that this issue is specific to PS Beta 27.9 on OSX Tahoe 26.5.2 

Has anyone else seen this on a different OS?
