Education | Enable sRGB Fallback for for Calibrated Monitors

Topaz Photo AI General

Hello,

I’m working with one my clients (I’m a Lightroom tutor) and he’s using Photo AI, Gigapixel, as well as the older Sharpen and DeNoise AI.

When using “Edit In” from Lightroom Classic, Lightrooms renders a 16bit TIFF using the ProPhoto RGB color space, and these files look fine in Gigapixel, Sharpen, Denoise — but in Photo AI, the colors are wrong.

Since this is a TIF file that Lightroom Classic renders before passing it on, the issue can’t be one of camera support or raw interpretation. It simply looks as if the ProPhoto RGB color profile isn’t interpreted correctly.

Once saved, the processed file shows the correct colors when back in Lightroom Classic.

This happens on a MacBook Pro M1. (I’m using a Mac Studio and cannot reproduce this issue.)

Here is a screenshot showing LR and Photo AI side by side.

Thanks for any insights.

TPAI has a long-running issue with color profiles: Color profile is off etc.
Toggling sRGB preview fallback may help, but the upshot seems to be don’t trust the TPAI preview vs. LrC.

Photo AI will either appear as the default display color space, or sRGB depending on how you have it set in preferences.

On both computers, the displays are color-calibrated, so a custom profile is in use.

This preferences switch is OFF on my Mac, and I see the correct colors.

The colors are correct in Gigapixel 8, Sharpen & Denoise, without any adjustments.

That’s helpful, thank you. My search did not unearth this older post.

Not sure why this is still a problem in TPAI.

The issue was fixed in Gigapixel, but why not in TPAI?

I have been contacted by support and they have requested the files to look at what is happening. HTH

Hello all,

It will be important to see a screenshot of the DEVELOP tab, with a confirmation of what color profile is set in the before. Suspecting that it is a Adobe color Profile, which is not what Photo AI will read. Photo AI will put the in-camera color profile. Once the file is back, you can put back a Adobe color profile if you want.

Send screenshots of your before/after and details on your exact workflow, and your camera model if you get any issues, to support@topazlabs.com and we can check that nothing else is happening.

Hello,

For any calibrated monitors, it will be important to enable sRGB fallback in Photo AI’s preferences here: Edit > Preferences > General > Enable sRGB Fallback, this will give the correct preview.

For any RAW files, it will also be important to use the RAW plugin path, which is File > plug-in Extras > Process with Topaz Photo AI - which will apply the in-camera color profiles, lens correction and allow for RAW Denoise access. Using the Edit in path, meant for JPEG files, will convert the file to TIFF, and revoke access to RAW Denoise. Using Denoise to remove RAW noise can create blotchy areas and artifacts, as edits are made on a TIFF, not the RAW file.

Send screenshots of your before/after and details on your exact workflow, and your camera model if you get any remaining issues, to support@topazlabs.com and we can check and make sure that nothing else is happening!
