Exposure Chart 1: f/stops and Shutter Speed
The numbers in this chart are set to an arbitrary relationship were f/8 @ 1/500 sec. is the
“correct” exposure chosen by the Photographer. Yet, all of combinations are the “correct”.
This is because as you go to the left of f/8 @ 1/500 as the aperture becomes twice as large,
the shutter speed becomes faster letting in half as much light as before. So as you go to the
right of f/8 @ 1/500 as the aperture becomes smaller by half, the slower shutter speed lets
in twice as much light.
f/2 f/2.8 f/4 f/5.6 f/8 f/11 f/16 f/22 f/32
1/8000 1/4000 1/2000 1/1000 1/500 1/250 1/125 1/60 1/30
Both the f/stops and the shutter speeds are at one stop intervals between each other.
1. With f/stops, the small numbers are the larger aperture openings.
2. With Shutter Speeds, the higher the number, the shorter the time.
3. In Aperture & Shutter Priority Mode the above relationship is maintained
when you change aperture or shutter settings.
4. In Manual Mode, you can change Aperture and Shutter setting independently
of each other, if you need ot create over or under exposure effects.
