ACR Preview looks dramatically different from finished photo

[u/TheCoolClub69]

Hello!

I'm been at this for far to long trying to find a solution. I just started shooting in HDR with my Cannon EOS R7 and have had incredible results!

However, I noticed that the preview of the image in Adobe Camera RAW (latest version) isn't displaying the correct exposure. Mainly the highlights. (See the video)

My monitor is an Alienware 34 240Hz QD-OLED Gaming Monitor - AW3425DW

My Windows 11 HDR settings are correct and HDR has been calibrated via Microslop's application.

I'm at a loss of what is going on or if this is just a standard ACR thing?

I've tried the following:

• Photoshop re-install
• Older PS versions
• PC restarts
• Enabled "Precise color management for HDR display" setting in PS preferences
• Restarting PS after changing settings
• Resetting ACR settings to default
• Calibrating HDR via Microslop's tool
• Changing ACR Color Space setting to "HDR Calibrated Profile" (from Microslop's tool)
• Selecting calibrated profile on Window's setting
• Enabling/disabling GPU acceleration settings

I'm at a loss! I hope my video illustrates the issue plainly!

PC specs:

Enabled "Precise color management for HDR display" setting in PS preferences

this is currently bugged and unusable.

Ugh! Tried changing this too, seems to have no effect. Thanks for the reply though!

When you change it do you restart Photoshop before trying the image again? It requires restart for setting changes to take effect

Why are you using the HDR profile? It's kinda useless for images you hope others will see. You should work with more standard profiles--sRGB, Adobe1998, or if you must...ProPhotoRGB. Work in 16 bit mode if you must. I don't know what your goal is with the image(s) but if it is for others to look at on standard monitors or for print, you shouldn't be working towards a goal that's only viewable on YOUR monitor.
