There is a difference between a "beginner" and somebody who is "curious about" a subject/topic/skill.
A beginner has started doing.
It's possible that a beginner understands all of the theory but has yet to begin really doing.
You don't have to be an expert with a camera to be a good photographer but you do need to understand the basics of the tool.
I'm a beginner as far as IR photography. I've shot some IR and processed some IR images.
I'm curious about DSO astrophotography. I've read several definitive texts on the subject which involves BOTH the actual capturing of images as well as the subsequent processing but I wouldn't call myself a beginner because I've yet to take image 1 of a deep space object.
In "real life" I was a professional s/w designer.
In "real life" I was a professional technical writer.
I have always avoided attempting to help "beginners" on photography forums because there are always so many other "experts" who are ready to pound the beginner over the head with how much they know.
So, to me somebody posting a question in a photography forum's beginner's section is somebody (most likely) struggling with some technical aspect of the camera and not somebody who has been happy as a clam taking (possibly quite good) photographs with their phone or with a point and shoot.
