I learned it the old way, i even went to an art academy for a while to learn photography before digital was good enough to replace it. And then you learn the hard way to make a coposition on a viewer that will give you the right picture. I don't do like many today, make a million pictures to get a few good ones, i mostly only take few pictures and know there will be good ones in it because i can judge it good enough from the viewer (an lcd display today) as we had to do that instantly. We did not get a second chance, so we learned how to get it right from start. That is something i miss from younger photographer who never worked full analog.
But that digital photography has a lot of advantages i totally agree. I still got my analog gear, but did not touch it anymore for over 20 years as digital is just better (except as effect maybe)
