Using the f/stop scale

Using the f/stop scale at the le, 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.
