I'm focusing here on the new characteristics of the Tone Curve in PhotoLab 8 - there is another video in the Mastering DxO PhotoLab Collection dealing in detail with the RGB curve as found in PhotoLab 7. Noticed a much better example of the tone picker being useful in my PhotoLab 8 Review!
This is really helpful - thank you. What I don’t understand though is when you were increasing and decreasing contrast on the colour wheel, why did it affect the colour patches at all? I thought changing contrast was about enhancing edges where colours butt up to each other? I can maybe understand that it would affect CYM, but not RGB?
The implementation of RGB curves affects both saturation and luminance in all products that I'm aware of. DxO sidestep this by offering the Luma Curve which affects only Luminance with a perceptual change in saturation rather than an actual change.
@ Thanks - but it was the contrast slider I was referring to - not curves. If something is say solid red, how can contrast in that red change - what’s it contrasting with? Ultimately it’s a technicality- just curious.
Thank you! It’s worth getting to know, you can get more control over smaller ranges of tone than is possible with the sliders. Black Friday - hang on in there!
I think you answered my question at the very end: why use the tone curve when there are so many other tools available that give you more precise control? I do see value with the new Luma curve, but in general, I avoid all global edits. I look forward to similar discussions with these other approaches.
Yes, I generally share your feeling about global edits. Depends on the RAW to some degree, but where I have a precise view of what the image will look like, local edits get me there.
Excellent thanks!
Thank you, glad it was useful!
Curves were once a game of darts for me. This one is a bookmark. Thanks, Chris.
Thanks! Glad this is useful.

Thank you. I will endeavor to make more use of the tone curve. Not sure if I'm going to last out until Black Friday before upgrading 😆
