Curriculum for Cinematography
Read American Cinematographer.
Check out this famous series of “master classes” KODAK Cinematography
Master Class. In this previously linked excerpt, it's John Seale who takes a bunch of students
through a scene from the film “Dead Poet Society”. And here you have
other bits from the same series. 

What you get is professional
film cinematographers working on set or in a studio with
students to solve lighting issues. It may be too advanced for you (I
don't know what you know), but this is the sort of work that happens
all the time on sets ... although only in the head of the DPs (or in
pre-production meetings when the script, the characters
and their motivation are discussed). 

And, I just found out, after a quick search, that the series is still ongoing!. Do yourself a huge favor and start watching it -- the old and the recent stuff.
Kodak, the old film stock company, still has some good stuff for students and budding cinematographers available on their website. Check this page out: it's a bunch of informative PDF etc. on cinematography, like how to read a slate, workflow, filters, etc. There's a lot it seems.
Work on film sets, and see how they light things. Ask questions. Take
notes. And then shoot your own stuff (short documentaries, short films), with/about your friends, family,
whatever. Take photos, digital and traditional, always on manual (learn to use light-meters).
Shoot black and white and then color, which is harder.
Also, it's not (ever) about the gear you use, but about your eye,
your taste, understanding color and light and framing in relations to scripts
(and experience on sets).
Watch the best lit films ever made, the small ones and the big ones
(mainly the small ones 'cause they have no budget to light things).
Look at classical paintings and ask yourself: where's the light
coming from? Why is it lighting this part of the frame and not this?
What is it saying? What's the story?
Finally, keep at it. Make connections. Show up early and leave late.
Make connections. Smile and work hard. Keep at it. Becoming part of a community of filmmakers is absolutely vital. If one doesn't exist where you live, create it.


And I say all this with an MFA degree from one of the best film schools in the US.
