The tech stuff is easy because most digitals do it all for you anyway - whether you want them to or not (and you can fix their mistakes (most of the time, but not all of the time with your graphics program (PMView in my case) but yellowed whites are a bitch and a half). No more balancing film speed vs f-stops and depth of field or creative cheating. You point the thing in the right direction and press the button and that's it.
Now if you're an artiste, the "right direction" is by nature and will produce ART - even if you're using a Brownie box camera. If you're not, you'll get crap with a high end Leica, Bronica or Nikon.
Therefore: the only thing to study is composition and style. If you have to study it, you aren't an artiste (and not a single artiste will own up to the decades of study it took), but can play one on TV.
