I've gone the other way from Les.

I started doing utterly boring nature (not landscape) pictures, then started portraits. While I was working on this (model tests for a new agency, since folded (nothing to do with me, I hope)), I realised I was shooting the lighting, not the people. So after a few years hiatus I started taking landscapes and nature the way I'd learned in the controlled studio: Shoot light.

I'm still shooting light, not nature. My latest project is IR film, it's really interesting to try to guess how the light will look on an IR photo!
