How to become a professional fly-fishing photographer, with Brian Grossenbacher

My guest this week is Brian Grossenbacher [42:45], one of the finest fly-fishing still photographers in the world. You've seen his work on the cover of many magazines and in Orvis catalogs. (Brian and I recently collaborated on a book entitled, simply, Trout, with his images and my essays. ) Learn how Brian's career changed from being a full-time fishing guide to a professional photographer and glean some tips on how to go pro yourself—or at least improve the quality of your own images. Along the way, Brian tells a couple stories that had me in tears of laughter as I was recording this.
