f/stop ≧

coefficient

flash-to-subject distance (m)

ISO film speed and coefficient

ISO film speed	100 or lower	125–400	500 or higher
Coefficient*	4 (14)	8 (26)	11 (36)

*Numbers in parentheses ( ) represent coefficient for foot measurement.

For example, with a subject located 0.5m (1.6 ft) away using ISO 100 film, this is how you would calculate the aperture:

f/stop ≧	4	＝ 8*
	0.5

*An aperture of f/8 is suggested. We recommend using the smallest possible aperture ( f/11 or f/16).

With a very light or dark-toned subject, you may not obtain a correct exposure due to the subject's reflection factor. Use exposure compensation to ensure correct exposure.

(See pages 60, 69.)
