Nikon 58-104 - Manual (Page 42)

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 actuai distance is 1.33 meters
(4.3 feet).
The distance scaies on the exposure
caicuiation chart and ienses are marked by
estimated distances underwater. When you
estimate the distance, read the fiash
shooting distance range from the chart
directiy.
In TTL flash mode
Read the fiash shooting distance range in
the “ m Fuii" column on the left of the scale.
For example, when shooting a subject
underwater at estimated 0.5 meter (1.6 feet)
using ISO 100 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.

Usable film speed range in TTL mode:
ISO 25 to 1000 for the Nikonos RS
