In photography terms, I consider myself to be quite technical - looking at photos and ascertaining how they were taken, what settings were used, how it was composed, and so on.
What makes a good photographer for me is when the photographer can take me away from asking "How?", but move to asking "Why?". This is a piece of work that's probably one of the most powerful I've seen for some time.
