Does Photo AI retain the color space of the original image?

Just curious 'cause I looked at a couple log files for Photo AI processing on RAW files. There are some lines that reference sRGB, which made me curious if Photo AI keeps the image in ProPhoto as Lightroom uses, or at least Adobe RGB as the image came from the camera…

Just FYI, you can choose either sRGB or AdobeRGB for in camera generated JPEG images it is NOT the color space of original RAW images as they don’t have a color space.

Photo AI will use the color space of the image passed to it to process, otherwise (in standalone mode) you can specify any color space for the resulting processed image.

I’m not sure what you mean. I have my camera set up for AdobeRGB. I shoot in RAW, which contains a JPG for convenience. What does the sRGB in the TPAI logs mean? I get darker pictures with changed WB when I get the DNG file back.

Make sure you are opening it in a color managed application. DNGs have no color profile, other type of output will use AdobeRGB as there is no option to change the color profile in Photo AI

The Logs are probably showing the monitor profile, check the EXIF data in the output file to see what the color space is.

If you are using LR just synch the settings from the original RAW. If you are using as a standalone it will never match your preview as it is a different RAW converter.

Sorry I missed that point.

I use LrC. Do you mean to activate “Embed Original Raw File”?

No, synch the settings you applied to the original RAW to the image file returned from Photo AI.

Photo AI will use the color space of the image passed to it to process

OK, that’s what I wanted to confirm… As long as a RAW or DNG image sent from Lightroom to Photo AI, exported or through the plug-in, will not be dumbed down to sRGB during Photo AI processing, and when returned to Lightroom the image will still be in the original color space, its all good.

I’m not sure WHAT’s going on in the rest of the replies, so I’ll stay out of all that…

I do the sync, or I prefer presets so I have better control over what I want. But that is not my point.
The returned DNG has another WB and is darker than the original unprocessed RAW (CR3). Correcting it is not enough. According to Topaz, this is a camera dependent issue that will be looked at. I just hoped you had a solution or workaround.

Just to be sure I’m understanding… As an example:
Take a RAW image, and in Lightroom, set the exposure to +4 stops and the white balance to 10,000.
Then, in Plug-in Extras select “Process with Topaz Photo AI.”
In Photo AI, none of your changes should be visible. Do whatever adjustments you want in Photo AI, then have Photo AI process the image and return the result to Lightroom.
In Lightroom, you should now have a .DNG returned from Photo AI, and your Lightroom adjustments should have been applied. Automatically. All the settings on the returned image should match those of the image you sent.

Is that not what’s happening?

I vaguely recall what you’re describing happening with a much earlier version of one of Topaz products, but there were a bunch of people reporting it, and in a later version it was fixed. I believe that was in a pre-Photo AI period though.

What camera are you using?

I have a Canon EOS 90D. I checked with every week’s update of Photo AI. With version 1.5.4 the DNG still comes back much darker than the original. This hasn’t anything to do with the color space though, so I discontinue this thread.
