$0.02Base2calls / 30d - GET/depth-of-field
Depth of field from focal length, aperture, distance and sensor: near and far limits, total depth and hyperfocal distance.
$0.02Base2calls / 30d - GET/exposure-trade
Hold exposure constant: change one setting (aperture, shutter or ISO) and get the other two compensations, in stops.
$0.02Base2calls / 30d - GET/exposure-value
Exposure value (EV) from aperture, shutter speed and ISO, the light level it suits, and equivalent aperture and shutter pairs.
$0.02Base2calls / 30d - GET/nd-filter
ND filter maths: convert between ND factor, stops and optical density, and get the new shutter time with the filter on.
