How do you calculate long exposure time?
How do you calculate long exposure time?
Count the number of increased stops. If it was two stops, for example (ISO 100 to 400) then you just add those two stops to the shutter speed (30 seconds to 2 minutes) after resetting the ISO back to 100 and the exposure mode to Bulb. These are reciprocal exposures (30 seconds and 400 ISO equals 2 minutes and 100 ISO).
