Objects underwater appear
closer than they actually are.
For
instance,
if
the
estimated camera-to-
subject distance underwater is 1 meter
(3.3
feet),
the actual distance is 1.33 meters
(4.3
feet).
The
distance scales on the exposure
calculation chart and
lenses
are marked by
estimated distances
underwater.
When you
estimate the distance, read the
flash
shooting
distance range from the chart
directly.
In TTL flash mode
Read the
flash shooting
distance range
in
the
"M
Full"
column on the left of
the
scale.
For example, when shooting a subject
underwater at estimated 0.5 meter
(1
.6 feet)
using ISO 1 00 film, set the aperture to f/22
or larger
(smaller
f-number) to get the
correct
exposure.
When taking pictures with the arm
removed from the bracket
Open the aperture one or more steps wider
(f/16)
than that
(f/22)
read in the
"M
Full
"
column on
the
left of the scale
.
•
Important
When
setting
aperture,
check the flash
shooting
distance range
first.
To obtain
the
best possible
color
reproduction
,
set
the
aperture
to the
larger f·number if available.
