Some of the greatest breakers of tradition in art were highly schooled in the traditions of art before they decided to break them - look at early Picasso paintings for example. Or early Renoirs, or early Caravaggios. Salvador Dali could paint "straight" if he wanted to, and so could Yves Tanguy. In photography, look at Edward Weston's work from the 1910s-1930- he was a Pictorialist! Same with Ansel Adams. His really early work consisted of contact prints of whole-plate glass negatives in platinum/palladium. You've got to know the rules and conventions before you can break them successfully - otherwise you're just floundering around.
