This MeetUp is a follow up to the MPC August 12 Education night. Ansel Adams and Fred Archer developed sensitometry for exposing and processing film at the Art Center School in Los Angeles, around 1939-40. These Zone System principles also apply for exposing and processing RAW digital media files.
We will be meeting at and exploring the San Francisco Theological Seminary where the rich architecture will give us many opportunities to work on understanding and fine-tuning how to apply the Zone system.
Having your own 18% Neutral Density Grey card, or some very very close facsimile would be a very good idea.
