iPhone Photography School interviewed Eric about his working process and photographic philosophy. It's an insightful piece in which he also shares three important points about documentary storytelling.
1: Select a story that is inherently visual.
2: Work on projects that you care deeply about, that move your heart.
3: Pick a subject that you have good access to.
This is an excellent read, and may give a sense of what a workshop with Eric will be like. He'll be teaching in San Miguel this June. http://iphonephotographyschool.com/eric-mencher/
