Is it possible to make curves plugins like you have photoshop, davinci, and red giant?

[Robin S. kurz]

No and yes. No, not with the standard options given to you by the apps. Yes, if you’re a developer and know what you’re doing. 🙂

Some of which have in fact built such plugins that you can buy. E.g. one from Natress, which is available through FX Factory from Noise Industries.

Thank you Robin, I may look into FX Factory.
