Something I am laminating and putting in my bag. It may seem trivial, but I can never remember what the full stops are for shutter or aperture.
This is info is helpful for calculating long exposures.

Also, I included 1/3, 1/2 and 2/3 stops for Aperture.

so you're admitting you suck at math then? :wave:
i keed i keed. I sometimes forget each aperture stop isn't double on the math end....

Not really, I mean, I know how to double and halve, but when counting down 9 stops from 1/15, 1/8 doesn't seem like a likely choice. I dunno, never really learned what a full stop or any of that stuff was. I am self taught and lucky I can turn my camera on.

Or going from Aperture of 5.6 to 8 doesn't seem logical either.

I guezz I jus suk at stuff and stuff

I'm self taught, I also memorized all those years ago. determining shutter speeds is funky since it makes jumps like 1/8 to 1/15 or 1/60 to 1/125, but not hard to remember.

Apertures are just a factor of root 2, although rounded.

I do think you learn those a lot faster if you start on a manual camera. The first camera I used was a Nikkormat FTn or some such nonsense my father's parents brought back from a trip to Japan.

That's 'cause its a diameter and it varies on the area of the circle. The fstop is a square root really. square 8 and 5.6 and it makes alot more sense. (64 and 32 )

Hey Thomps6s,

You still got this pics of this table. It is not showing up on my machine?

shutter speeds in stops:1/8000 1/4000 1/2000 1/1000 1/500 1/250 1/125 1/60 1/30 1/15 1/8 1/4 1/2 1 2 4 8 15 30

apertures in stops: 1, 1.4, 2, 2.8, 4, 5.6, 8, 11, 16, 22, 32, 44, 64

there are half stops between each or 2 1/3 stops between each.
