Thanks Robin. Superb explanation, at last (6 months later...) I understand what this tool is doing instead of randomly twiddling until I (just sometimes...) I get what I want.

Finally, I have a better understanding of curves. Thank you.

Great explanation - Thank you!! This has been troubling me for a while and learning-by-doing wasn't exactly doing it for me! Haha... Thanks again!

Thank you Robin. I’m getting my head around Affinity Photo and this is very helpful to my understanding of the curves tool. I find your tutorials very thorough and easy to understand. Thank you for taking the time to produce them.

Many thanks Robin - I really do find this approach useful. Rather like our camera systems, I think most of us tend to get rather habituated to the few editing apps we regularly use (eg I mostly use ON1 and Affinity Photo) but explaining the underlying principles rather than just demonstrating editing techniques in different apps, leads (certainly for me as a relatively new photographer), to a firmer understanding rather than being slightly baffled by the less familiar interface or layout of editing apps we don't use.

Thanks Robin. Very clear explanation which has certainly improved my understanding of the tool and how it works.

These are great tutorials, Robin. Thank you!

Thank you. I've used curves, but I never really understood what they were doing.

Thanks for these videos, they're really useful.

Very helpful, thanks a ton Robin!

Robin, this is really great tutorial but I have to agree with Tony Greenwood and maybe you had to explain all tools in Curves Adjustment Panel in Photoshop and their practical usage on some examples. Keep going with this great tutorials!

nice thank you ❤

I have seen in some tutorials they put two curve adjustment layers. And its usually one for lighter tones and one for darker tones, and between the two layers there are other adjustment layers. Why do they do that?

Another Photoshop supremacist, we vote with our feet Affinity is better value and it is not simplistic.
