Chris, thank you for your heart felt appreciation and tribute to Ansel, I enjoyed it immensely and personally think that just about every photographer working today owes him some degree of thanks for his influence. Whilst I prefer other photographers work I have AA to thank for his influence in my use of the Zone System even though I apply it in a totally different way to the great man. However, it was reading Ansel's views on pre-visualisation that was the most significant of his influence on my photography for his words made me go out and work to perfect that very important aspect of making photographs.
