I’ve just downloaded the latest version 3.4.2, I think) and the 2 photos I’ve worked with to try to sharpen have both had their colour changed, quite significantly.
I’ve only been using TAI for a few days, but this didn’t happen before this update.
TBH, one photo the colour change is arguably an improvement, but the other definitely not. But the point is I didn’t ask for any colour change.
How can I stop this happening, or undo the colour change?
Even if I love the sharpening, if I don’t like the colour change I can’t use the updated image.
I’ve noticed this taking photos from Lightroom into Topaz and back. Resetting the color profile restores the colors.
Prior to sending the photo to Topaz, note the color profile in Lightroom (e.g., “Adobe Color”)
Apply enhancements in Topaz
After exporting the photo back into Lightroom, the color profile may show the same setting used on export, or it may have something different (I’ve seen both cases) - either way, the colors are obviously different
Change the profile to anything else and then switch back to the original setting from step 1
I assume you’re not letting autopilot do colors - that’s about the only reason I’d expect differences between images.
Are you working on raws or jpgs, and which camera? tpai’s raw conversions have had issues with certain cameras, especially when newish (my sony a6700 arw’s were all green for a while, and tint and temperature were reported back to Capture 1 completely wrong). These tend to get fixed eventually (see release notes over the previous versions, and search on your camera model, especially if it’s fairly recent).
And looking at the release notes, camera profiles might be applied as well, whether this is also done by your main processing software could also yield color differences. I don’t know if you can change/disable this behavior.
I get the sense that passing raw files amongst processing programs is an easy way to generate color shifts.
I’m not sure about Apple Photos, but with Capture1, the general system philosophy is to write dng’s with no/minimal transforms vs the raw. So I can edit an arw in C1, but if I send it to TPAI as a dng, it loses all of the edits in being written (by C1) to dng so what I get back from TPAI is different than what I intended to send. I can apply the original arw edits to the new dng but TPAI does some things with white balance and colors (including losing bit depth at near-white and near-black) such that the dng still looks different.
The only way I know around this is to send TPAI a tif (or jpg), which precludes raw denoise but eliminates color shifts, lens corrections, etc. since white balance, gamma, actual rgb colors, and other demosaicing stuff is baked in before it gets to TPAI.
