I would be a lot more impressed with PL if they could figure out how not to trash your image folder with sidecar files.

Sidecars are optional in PhotoLab. If you don't want them, disable them under Preferences > General > Correction. The same info is always stored in the database.

In PL 7, there is no such capability in "General>Corrections" ...

I can see it there quite clearly in PhotoLab 7 for Windows.

Quoted message:

That only relates to geometric correction. Under Settings>Advanced - there is an option
there are options on Sidecar files of "automatically export" and "automatically import."

Maybe that's the Mac version.

Quoted message:

However, the meaning is somewhat unclear. So I guess I'll need to experiment a bit.

Yes, do that.

Yes. The options are under Preferences in PL 6, and why they were moved in PL 7 is not clear to me. As I understand it, the sidecars are meant as a backup to the database, and I imagine that they can be used in the event that the .dng and .dop files are moved to another folder, as the values in the database save the full path to the original folder of the .dop file. I have no idea why!

I finally wrestled PL7 to the ground kicking and screaming and it is no longer polluting my image file with the sidecar files. There set up is not the most obvious around. But it works it seems.

No it wasn't. It provided real data to compare software.

Sorry, I was in a bad mood that day ... being a grumpy 84-yr old man ...

Yep, I'm a numbers guy which sometimes excites little or no response amid much discussion on how something "looks", grump.

I was offered a free trial of Luminar Neo, so I thought I'd see how it did. I also use Adobe PS and ON1 Photo Raw (I also have Capture One, but that's over a year old now).
I have a standard very noisy image that cleans up OK in Adobe Camera Raw and not quite as good in ON1. So, here's the results:

I leave you to draw your own conclusions, but I'm not buying Luminar based on that.

Bear in mind that the color saturation is much higher in the Neo version, so naturally, that could make chromatic noise stand out more, even if it really isn't more.

What happens when color saturation is normalized? I bet they will be more similar than they are here.

How would you normalize color saturation, John?

I use the GIMP and can edit saturation-only in HSL or HSV ... or chroma-only in CIE LCH.

Then I could compare the degree of similarity by using 'difference' blending in Layers ...

Here's Neo vs Original compared with Neo vs Original (left) but with normalized Saturation in HSL (right):

I couldn't compare the degree of similarity by using 'difference' blending in Layers because Alan posted the images at different sizes.

The images were just screen grabs. If you want the originals, I can post them - but they may be on my system at home (I need to check) and it's shut down.
