Have fun with your camera. Find out all it can do by taking several shots of the same object while using all the different settings to see how they work.
If you like using auto or program, use it! If you know full manual including ISO, aperture, shutter, etc etc etc .. I don’t think that means you ‘aren’t allowed’ to use A or P any more, as if it were punishable.
Sometimes I put it in auto just for the sake of instant readiness in case ‘that’ photo opp comes up and I wouldn’t have time to fiddle with anything.
Who’s judging, anyway?
