Photoshop 26.11 on macOS Preview for Image > Adjustments like Shadow and Highlight doesn't work

[モカ]

I think photoshop 26.11.0 may preview of shadow and highlight doesn't work.
Mac OS 14.7.8

If you go to Photoshop 2025>Settings>Technology Previews, uncheck Enable Modern User Interface, then restart Photoshop, does that make any difference?

Hello to all,

I can't make adjustments in Photoshop with the Vibrance/Saturation sliders for a couple weeks now, they move but do nothing else. Any suggestions?

PS Version 26.8.1

iMac M4, Apple Sequoia 15.5

Thanks

[Erik Bloodaxe]

Are you referring to Camera Raw rather than Photoshop?

[ML2travel]

Photoshop

I should add, since I just discovered this, that I can make the adjustments but can't see any preview beforehand even though Preview is checked.

Hi, @ML2travel , can you please share a screenshot of what section of PS you are working with? Is it a Panel, a menu selection, what?

That would help us a lot.

Thanks,

Image > Adjustements > Brightness/Contrast

and

Image > Adjustements > Vibrance

These two ^ don't show preview in real time. Have noticed this more than 3 weeks ago, was busy to come here and create a thread about it.

I have the 26.10.0 release of Adobe PhotoShop

@LuminousSky is your GPU active? (Settings/Performance/Use GPU) if that is off, live preview will not work. 

[LuminousSky]

Is that the: "Graphics Processor Settings"? I can't find something like GPU.

[LuminousSky]

Thanks! Now it works. Had causing me some issues in the past, that's why I had to turn it off. If I can remember well something regarding the AMD system I am on? Can't remember now.

[Kevin Stohlmeyer]

Could be an issue with your specific GPU - turning off the setting temporarily is a band-aid fix and leaving it off is more detremental than beneficial. Ifyou still have issues with you graphics card, run all available driver updates or post a new thread regarding specific issues and details. Glad this worked for you!

PS version 26.11 now. Any pop up menu with the new styling:

- Brighntess/Contrast

- Shadows/Highlights

- Exposure  

- Vibrance

- Color Balance

- Channel Mixer

- Selective Color

- etc...

I use either Curves or Shadow/Highlight in nearly ever image I process. By having the preview in Shadow/Highlight checked, you can view the effect of the sliders. After updating to v26.11, that went away. I had to roll back to v26.10 to get that ability back. I wondered if anyone else is experiencing this problem, or if it's unique to my PC. Thanks.

[Stephen Marsh]

It works for me in 26.11 on Windows 11.

Perhaps backup your custom actions and other presets and reset your preferences.

[ML2travel]

What would help a LOT is if Adobe would simply tell us to uncheck Enable Modern User Interface under Techonolgy Previews, rather than wasting a lot of time inventing work arounds on our own.

Hi @ML2travel  - Thank you for reporting this issue. Apologies for the inconvenience caused.

Since this issue is Photoshop related, I have moved this thread to Photoshop forum

Thanks,

Varun

Hi!

Can you give us a little more information and show us a screenshot of your window and all of the panels? What are the steps you are following when this happens? If you can tell us more about your process and when/how this happens, we will be able to help you more effectively.

Thanks!

Kevin, is that Edit -> Preferences -> Performance -> Use Graphics Processor? I tried that and I'm still not getting previews on Brightness/Contrast, Vibrance/Saturation, Exposure or anything else.

[Ged_Traynor]

@ctondro try disabling this option in the preferences and restarting Photoshop to see if it helps

[ctondro]

Thank you. Restarting alone allowed the previews to work, after enabling the graphics processor. But I will keep this setting in mind for future problems! I appreciate you pointing it out to me.

[ctondro]

Thanks, Jeff. On my version of Photoshop it's Edit -> Preferences -> Technology Previews. You were correct that unchecking Enable Modern User Preference and restarting Photoshop brought back the previews. And I didn't need to enable the Graphics Processor. I really appreciate the information.
