Keep in mind that photography is also an industry and yes, a hobby. Most folks taking pictures are weekend photographers to whom photography is a way to stay busy. Though these folks are having fun, which in itself is a good thing, there is a really big step to go from just having fun to making art. Yeah, there is of course subjectivity and "in the eye of the beholder" stuff, but still, serious art takes serious effort and time. And a lot of art education. Yes, there's Vivian Maier and Mike Disfarmer, two autodidactic photographers who created great work, and maybe photography lends itself more to intuition than say, playing the violin. But the vast majority of great photographers have been and still are full time.
"Intuition"
And there you pretty much have it. Intuition, and a natural eye for shapes.
Technical skill is learned, in the manner that anyone learns mechanical/technical stuff, best by watching and then trying it yourself. Then, when you have the understanding of how to manipulate a computer programme (darkrooms are different), you are ready to go.
Sadly, none of that makes you a creative photographer; for that, you still have to depend on intuition which, you either have or do not have.
I wrote that darkrooms are different. Indeed they are, and the principal difference is that unlike with a computer where you can layer and layer until you think you got it right, the wet stuff is far more visceral, and you are playing with time, temperature and concentration/exhaustion of chemical soup. On top of that, you have to get to know your safelight fairly intimately before you can trust it, not to not fog your papers, but to let you see what your work will resemble in the harsh light of an inspection lamp or daylight.
Maybe darkrooms demand skill, intuition
and love.
