Example 2:
When shooting a subject underwater at 4m (1 3ft) with
the wide-flash adapter while using ASAIISO 100 film ,
you must use f/2 .B.
When several f/stops are useable at a specific flash -
to-subject distance , make your selection by taking the
desired depth of field and speed light recycling time into
consideration.
TTL Auto Shooting Range
Example 3:
When shooting a subject on land at 2m (6.6ft) without
the wide -flash adapter while using ASAIISO 100 film
and you want the largest depth of field possible, select
f/1 6.
If you want to minimize recycling time as much as
possible, select f/2 .S.
In the TTL automatic mode, the S8-102's useable
ASAIISO film speed range is from ASAIISO 25 to 400,
its useable aperture range is from f/2 .B to f/22 , and its
flash-to- subject coupling distance range is from O.3m
(1 ft) to 22 m (72.2ft). However, the relationship between
the useable aperture range and the flash-to-subject
coupling distance range varies according to the
ASAIISO speed of the film in use, the type of photo-
graphy (on land or underwater), and whether or not the
wide-flash adapter is being used .

*
These figures should only be used
as a
guide because flash·to -subject coupling distance ranges are affected by the existing conditions
(water quality, surroundings, subjects, and
so
on). For best results, test-fire the flash before actually shooting.
