We all evolve. Evolution is more likely than revolution (but we can hope). Seeing your own evolution for what it is, a gradual refinement of process (style) is a luxury that digital imaging affords us.

My own evolution, or refinement of technique seems to be zeroing in on specific types of light.

Most things are interesting with the right light and many interesting subjects lose impact in poor light.

The cool thing about light over subject, is that it can be found anywhere.
