RE: METADATA MONDAY by @derekkind - Photo Games Week #2 Day 1
I was thinking of it in terms of stops - and I should probably write this in the rules - one stop difference between 1 and 2 seconds, three stops to 1/8. Otherwise you could argue that 1/4000th is closer to 1 second than 2 seconds is.
yeah, I am a little confused now. I don't know what stops are (in shutter speed), but I know that simply measuring the exposure time, 1/8th of a second is closer to 1 second than 2 seconds. I am probably missing something..
Stops are a doubling (or a halving). 2 seconds is one stop longer than 1 second, while 1/2 seconds is one stop shorter. 1/250th is one stop longer than 1/500th, which is one longer than 1/1000th, etc. Aperture is measured in the same way, in that each stop of aperture lets in double or half the amount of light, it's just not obvious because of the way the numbers read: 2.8, 4, 5.6, 8, 11, 16 are all one stop apart.
I see, good to know! Thanks for explaining. :) Now it makes more sense.
Good! :)
