Hi P, Welkom at Lula.
I have a few tips, maybe they are helpful.
Forget the technical stuff (for this moment) and switch your camera to Auto. (No joke) and forget post processing for the moment.
Take your camera on a hike and shoot what you find interesting or beautiful . That’s a nice start to get a grip on composition, framing, etc.
Later on, you will walk into the limits of shooting automatic and you will roll into a more technical approach.
A very interesting exercise: cut out a sensor sized hole in a piece of cardboard and use this to learn how to frame, it will give you insights in perspective, focal length, etc.
Holding the cardboard close to your eye is wide angle, holding it farther away is tele. Use your feet to see how the perspective changes with your position.
It’s a stupid exercise but worth doing.
Succes.
