Ya it fooled me a bit too when he first asked but I guess if you go strait to something like dehaze it could fool someone in to thinking its not really working if you make no changes. You go to dehaze and select preset, auto, give it a name and then leave all parameters blank so it applies to all images. If you had made a change then its like a style with inactive modules ready to activate with your settings, the use case being an inactive module with your custom settings when you do activate it. It semantics but it might be worth adding to the manual that he state of the module is saved in both presets and styles…I’ll have to double check but I don’t think that is currently in there and at least for this user he thought that creating the preset would apply the module with defaults… I guess as almost any other action performed in the module does activate it?? Maybe just a one off case…
