Convert decibel (amplitude)s to stop (photographic)s
How to convert decibel (amplitude)s to stop (photographic)s
Convert through a plain ratio: decibel (amplitude) → ratio → stop (photographic). Logarithmic units cannot be converted by multiplying alone.
Decibel (amplitude): For voltage, pressure and other field quantities. 6 dB is roughly double the amplitude — and the same fourfold change in power.
Stop (photographic): One stop doubles the light. Identical arithmetic to the octave.
