Objects underwater appear closer than they actually are.
For instance, if the estimated
(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
Iunderwater at estimated 0.5 meter (1 .6 feet) using ISO 100 film, set the aperture to f/22 or larger (smaller
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.
+Note
Usable film speed range in TTL mode:
ISO 25 to 1000 for the Nikonos RS
ISO 25 to 400 for the Nikonos V
