Nikon SB-16 instruction manual Shooting Mode Selector @l, TTL through-the-Iens automatic operation

Shooting Mode Selector @l

The shooting mode selector on the back of the SB-16 has five click-stop settings. Directly above the selector (read - ing from left to right), there are the blue and orange dots for non-TTL automatic operation, two white dots in the middle indicating MD (Motor Drive) and M (Manual) operation respectively, and a white square at the far right which is for TTL operation.

As soon as the SB-16 is tu rned on , one of the appropriate LEOs (green for TTL and red for all the rest) above the selector lights up to indicate the setting selected.

Usable shooting modes depending on the combination of the type of the flash unit and camera are as listed on page 5.

TTL (through-the-Iens automatic operation)

This mode provides automatic through-the-Iens (TTL)

control of the flash exposure at any aperture from fl2 to fl22 to match the camera-to-subject distance: the farther away the subject, the more light emitted by the flash unit; the closer the subject, the less light given off. Because the exposure is measured through the lens, no exposure compensation is required in off-camera and/or bounce-flash operation or even with a teleconverter or filter attached to the lens.

This setting is also used for programmed TTL auto opera- tion with F-501/N2020 and F-301/N2000.

A (non-TTL automatic operation)

In the non-TTL automatic (A) mode, the light output of the flash varies automatically to match the flash-to-subject distance, but instead of the light being measured through the lens, it is read by the light sensor on the front of the SB-16. At any film speed setting , you have a choice of two working apertures indicated by the blue A1 and orange A2 aperture indicator lines on the bottom of the exposure calculator dial.

M (manual operation)

At the manua~ ~M) setting , the SB-16 fires at its maximum light output regardless of the flash-to-subject distance. When it is difficult to obtain correct exposure on auto, I. e , when the brightness of the background affects exposure strongly, use the SB -16 on manual. In the manual mode, exposure should be determined with the exposure cal- cu lator dial or with the guide number equation found on page 30 .
