Exposure does not match in Lightroom and Photoshop

Just in case:

Display profile issues on Windows

At least once a week on this forum we read about this, or very similar issues of appearance differing between applications.

Unfortunately, with Microsoft hardware: Windows updates, Graphics Card updates and Display manufacturers have a frustratingly growing reputation for installing useless (corrupted) monitor display profiles.

I CAN happen with Macs but with far less likleyhood, it seems.

The issue can affect different applications in different ways, some not at all, some very badly.

The poor monitor display profile issue is hidden by some applications, specifically those that do not use colour management, such as Microsoft Windows "Photos".

Photoshop is correct, it’s the industry standard for viewing images, in my experience it's revealing an issue with the Monitor Display profile rather that causing it. Whatever you do, don't ignore it. As the issue isn’t caused by Photoshop, don’t change your Photoshop ‘color settings’ to try fix it. 

To find out if the monitor display profile is the issue, I recommend you to try setting the monitor profile for your own monitor display under “Device” in your Windows ‘color management’ control panel to sRGB temporarily. 

You can ADD sRGB if its not already listed. 

And be sure to check “Use my settings for this device”.

(OR, if you have a wide gamut monitor display (check the spec online) it’s better to try Adobe RGB here instead).

Quit and relaunch Photoshop after the control panel change, to ensure the new settings are applied.

If this change fixes the issue, it is recommended that you should now calibrate and profile the monitor properly using a calibration sensor like i1display pro, which will create and install it's own custom monitor profile. The software should install it’s profile correctly so there should be no need to manual set the control panel once you are doing this right. 

Depending on the characteristics of your monitor display and your requirements, using sRGB or Adobe RGB here may be good enough - but custom calibration is a superior approach.

Still got problems?

If you want to try a method that’s proved successful to rule out many an issue we see with Photoshop, you can reset preferences:

Note: Make sure that you back up all your custom presets, brushes & actions before restoring Photoshop's preferences. Migrate presets, actions, and settings

I hope this helps

OK. The way you describe it now, it sounds like the only other known issue that might fit - which was a problem in one specific Canon camera profile. IIRC users were reporting something very similar to what you describe here.

That too has been fixed , and indeed the fix is the change you now see. The original profile rendered the image way too dark.

You have a version mismatch. Update Lightroom to the current version, which is 10.1.

There was a bug in the Lightroom handling of third-party/custom camera profiles, which weren't correctly transferred to ACR. I believe it is fixed now. The standard/native camera profiles weren't affected.

If that's not it, you have a defective monitor profile, which can also give these symptoms. Either way, it has nothing to do with document profiles. There is no need for Lr and PS color profiles to match. Any profile out of Lightroom will be correctly handled by Photoshop.
