Using the f/stop scale
Using the f/stop scale at the left, moving
one step vertically is equal to a full-stop
change. Moving one step diagonally is
equal to a half-stop change.
Half a stop is basic for setting the
aperture in this step. When using a
0.3 stop setting camera, adjust the
aperture by a value as close as possible
to a value in the above table and use
the aperture around the f/stop scale.
For precise photography, bracketing is
recommended.
Example:
Starting at f/8, if you decrease the
exposure by a full stop, you get f/11.
If you increase by half a stop, you get
f/6.7.
