My topic title is clunky but what I'm trying to understand is how 1 stop of light is calculated in all the different measurements.
I'm guessing there is a chart somewhere but I couldn't find anything that seemed reliable or that had any explanations to what the math was.
What are the increments of one full stop for F-Stops is F2 to F2.8 is that one full stop and what are the stop increments before and after that and how are they calculated.
What are the increments of one full stop for shutter speed do you just double it? 1/50 to 1/100 is that one stop?
What are the increments of one full stop for ISO/ASA is 100 to 200 one stop? is 160 to 320 one stop? do you just double this as well?
I searched the forums but the search function didn't turn up what I was looking for. If this is already discussed can you please point me in the right direction.
