Sharing first edit and sharing for edit

Just starting with DT (and photography in general) I have a problem with bottom left where stuff is purple for some reason in my edit, still struggling with DT edit process .
I also would like to see what can you guys do with all the skillz.

I opened the image at default scene referred settings in DT 4.9 (4.8 should give same result) and had lots of green as expected for a forest. But then I got the color calibration module to set the color to a neutral color based on the whole picture area. That gave me a blue magenta which was counterbalancing the areas of green/yellow in the image. See screen shot for the two views I saw.

I just loaded your xmp file and the cause of your issue is what you have done with the color calibration module. You have asked it to take a very green scene and turn it neutral and that is the source of your color problem. My solution would be to leave the color balance at default and use rgb color curves to tweak the individual RGB channels to give the color you are pleased with. Others may have better or different solutions to suggest.

And what is the purpose of this information? Do you plan to provide your play raw of this image?

You need to include in your original post the text it pre populates for you or similar license.

My try in RT from raw with Retinex at default setting:

Was interested in the purples at bottom left so extracted the hues for the posted image and my converted raw.

It looks like dt was over-actively set, as some have already said. For information only - no criticism intended.

OK I know you tried to be helpful but this confused me allot and I’ve just realized I know nothing about image processing.
And that i need to invest time in learning image processing fundamentals, cuz at this point i just pull sliders and hope for the best.

Poke around here a bit and check out some of the tutorials…its a good overall primer on what you need for context…

https://www.cambridgeincolour.com/

Then scan the online manual for the key modules that you use in DT and also look at the section on workflow so as to get a sense of the approach that DT takes to image formation…

I apologize for the confusion. I was trying to help with the purples at the bottom left of your posted image which were not there in my un-processed raw conversion.

The pixel color in an image file is stored as values of red, green and blue (RGB), also known as channels. These channel values define the pixel color seen when displayed on a monitor screen. Many editors allow viewing and/or adjustment of the channels separately.

Another way to represent a color is by three channels such as hue, saturation and lightness (HSL) where Hue H determines the color appearance for example yellow. See:

Some editors, such as the GIMP, allow the image to be decomposed into HSL channels, displayed as three separate review images. To show only Hues independently of Saturation and Lightness, one can fill the S and L channels with say light gray and then recompose so as to look like what I posted above, showing only the Hues - thereby allowing one to see for example where all the purples are exactly … in your case, on the tree trunks.

This activity is useful for analysis but, obviously, is no good for post-processing.

I hope that this helps a little, Ty.

So that you can see exactly where your edits made wrong colors, I have merged the hue image with your posted image which might tell dt users something:

Wow and thank you kind sir.

Thank you

You can do something similar in DT to check…you leverage the parametric mask channel (Hz) and hover on the slider and use the C key… and you will get a hue map

for this edit for example doing this early in say exposure gives roughly the starting point and then you can add an instance after output and do the same check to see where the image has gone wrt hue…its similar to what you have shown…
