The following explains how to obtain the aperture using the two twin flash units
with a power level of 1/1 at 1.5 m flash-to-subject distance and at ISO 100.
1 Draw a vertical line upwards from the flash-to-subject distance until it reaches
the flash power line that corresponds to the set power level ().
2 Draw a horizontal line leftwards from until it reaches the vertical ISO line
corresponding to the camera used ().
3 Draw a diagonal line from upwards and leftwards. The result indicates the
aperture that will provide the proper exposure ().
In this case, the proper exposure can be obtained by setting the camera’s aperture
to f/16.
The figures in parenthesis are employed when only one twin flash unit is used.
