Maybe this will help and make it more clear.
In PS select the curves adjustment layer. Use the color picker and if it hovers over a spot in your photo that puts a dot right in the center of the curve, it is neutral gray. Almost all photos will have something like this or something very close. With experience and time you will be able to just see these places and the selection will become easy. After you do this edit, you can do the others to make it a great photograph.
Thank you this is a really good advice that I needed. That means that in this case the point has 50% grays and if the values are 100% equal that mieans neutral gray. I'm right?

Success! You got it.

And, this is exactly what we will endeavor to do so hold on tight!
Right off the top photo is correct. The bottom one is junk. Now let's try to figure out why.
If your monitor is off as one poster suggests let's take care of that right now. If on a Windows machine, Mac has similar adjustments, look at your grayscale. That is the single most important thing to have correct. You have the ability to adjust it as is. You do not need any additional software or gadgets. Secondly, the the brightness and contrast again adjustable in Windows. Most people set their monitors too bright.
All post editors do their own thing. LR, DPP4 or Capture One, which you should probably switch to LR/PS, are all different in how they interpret a Raw file. Canon does not document its Raw files. Nobody else knows how Canon does it. It is not even the same for any given camera in the Canon line of cameras. A 6D could be different than a 6D Mk II for instance. But all 5D Mk III's are identical, all 1Dx Mk II's are identical, etc.
All post editors read the metadata tag file embedded in the Raw file. They use that to create an image that can be displayed on a computer monitor. The metadata tag is read from the settings you did in your camera. But they are not part of nor do they alter the original Raw file. The big advantage of Raw is the greater range of adjustments. This is due to the fact a jpg deletes actual data to compress the file as it process it. The real bad part is that data is lost forever. It can not be recovered.
"...where the white balance was set from the lump of the bright pice of model shorts .."
This was a poor choice. Especially when you had a good place in the gravel to the right of her back. Le me show you.
First this is her shorts used as a grayscale adjustment point in ACR.
This is using her shirt fo rgrayscale.
And last, using the gravel behind her back.
On my monitor this looks correct. But are you beginning to understand how this works? She is a lovely young lady, BTW.
If you are truly wanting to get into professional looking photography I strongly suggest you get LR and or PS, better yet, get both. Capture One and actually all the rest are for amateurs.
