Photography Exposure And Depth Of Field Calculator
Photography Exposure And Depth Of Field: a planned Super Calculator tool. Stub page: the tool, its formula and a worked example are not published yet.
Photography Exposure And Depth Of Field Calculator is a planned calculator in the lifestyle section of Super Calculator, covering miscellaneous.
What this calculator will compute
Inputs: aperture (f), shutter speed (s), ISO (n), focal length (mm), sensor size (label) and subject distance (m).
Outputs: exposure value (EV), equivalent settings (table), hyperfocal distance (m) and depth of field near and far (m).
Formula, recorded as scope and not yet verified against a primary source: Exposure value equals log base 2 of (aperture squared divided by shutter time), adjusted for sensitivity, and equivalent exposures share the same value. Hyperfocal distance equals focal length squared divided by (aperture times circle of confusion) plus focal length, where the circle of confusion depends on sensor size.
