Nikon D2Hs manual Flexible Program, Exposure Program

Flexible Program

In programmed auto, different combinations of shutter speed and aperture can be selected by rotating the main command dial (“flexible program”). All combinations produce the same exposure. While flexible program is in effect, an asterisk (“*”) appears next to the exposure-

mode indicator in the top control panel. To restore default shutter speed and aperture settings, rotate the main command dial until the indicator is no longer displayed. Default settings can also be restored by turning the camera off, selecting another exposure mode, performing a two-button reset ( 126), or choosing another setting for Custom Setting b3 (EV step; 181).

Exposure Program

The exposure program for programmed auto is shown in the following graph:

ISO 200; lens with maximum aperture of f/1.4 and mini- mum aperture of f/16 (e.g., AF 50 mm f/1.4 D)

Shutter speed

The maximum and minimum values for EV vary with sensitivity (ISO equivalency); the above graph assumes a sensitivity of ISO 200 equivalent. When matrix metering is used, values over 171/3 EV are reduced to 171/3 EV.
