There are all kinds of places to continue to learn and expand as a photographer. There are full on degree programs, photo expeditions, seminars of all types, but one I always suggest looking into (even though I have never been myself) is Santa Fe Workshops. They have a fair amount of credibility in my book because of the caliber of people they attract to teach as well as the varied programs they offer. You can take course in just the areas that you have interest. And spending a week in Santa Fe, NM ain’t bad either!

I get no kickbacks for the recommendation, but check them out anyway!
