I enjoy strolling around San Francisco doing "street photography." And I most often use an older camera without built-in light meter, without range-finder. This requires that I get "all set up" for the shot before I even exists.(posted 9377 days ago)When approaching an area (street, alley, park), I use a hand-held meter to decide on exposure I'm likely to encounter. Yes, I make this decision based on the Zone System. Also, I decide on my most probable focus / depth of field requirements. Oh yes, I most often use ASA 400 film rated at 200 or -- in low light conditions -- I use Neopan 1600 rated at ASA 800.
Then I walk along and shoot at whatever interests me. I think of this technique as converting a 45 year old, fully manual camera into a point and shoot.
