Response to EV values on a light meter

from Conrad Hoffman (choffman@rpa.net)
From the dial of my venerable old Weston Ranger 9, at a film speed of 125, EV 14 equals 125 candles per square foot. The manual says to multiply that number by 4 to get footcandles. They also say the reading should be taken from a piece of white paper, so I'm not sure how accurate it is. It's also 1/125 at f/11, so you can figure out any other setting from that and the info posted above. The EV system is supposed to be absolute, and shouldn't vary from meter to meter.
