During the celebration in Yosemite all of Ansel's former darkroom assistants were invited, Iris Arts was commissioned to film each of them.  The theme of each interview was structured focusing on what they had learned from their time with Ansel Adams, how that had impacted their photographic work, and what they had passed on to their students..  The idea of this progression was to look at what we learn from our teachers/mentors and what knowledge is then transmitted to our students.
