Formulas
|
depth of field (near) = hyperfocal distance x focus distance hyperfocal distance + focus distance
depth of field (far) = hyperfocal distance x focus distance hyperfocal distance – focus distance
Hyperfocal distance = focal length2 circle of confusion x f-stop
exposure time = shutter angle 360 x frames per second
f-stop = focal length of lens diameter of lens opening
feet per minute (16mm) = frames per second x 60 40
Feet Per Minute for 35mm, 3-perf Format feet per minute (35mm, 3-perf format) = frames per second x 60 21.33
Feet Per Minute for 35mm, 4-perf Format feet per minute (35mm, 4-perf format) = frames per second x 60 16
Meters = (feet x 12) + inches 39.37
feet = meters x 3.2808
Screen time = camera running time x frames per second 24
