EXPOSURE MODES

The four exposure modes allow extensive control over image making. Programmed AE gives carefree operation, aperture and shutter priority allow photographers to maximize exposures in different situations, and manual exposure provides complete freedom in controlling the final image. See setting the function dial section on page 48.

P

Program - the camera controls both the shutter speeds and aperture.

A

Aperture priority - the photographer selects the aperture and the camera

sets the appropriate shutter speed.

S

Shutter priority - the photographer selects the shutter speed and the camera

sets the appropriate aperture.

M

Manual exposure - the photographer selects both the shutter speed and

aperture.

PROGRAM - P

The programmed AE exposure control uses luminance and focal-length information to ensure perfect exposures. The sophisticated exposure system allows the photographer the freedom to shoot without having to worry about the technical details of exposure settings. The shutter speed and aperture values of the exposure are displayed on the monitors and data panel. The shutter speed range in program exposure mode is 8 to 1/4000 second when camera sensitivity is set to auto (p. 71). If the brightness level of the scene is outside the exposure control range of the camera, the shutter-speed and aperture displays will turn red on the monitors and blink on the data panel.

The program line adjusts with the changes in focal length of the zoom lens. The camera is programmed to maximize depth of field in the wide-angle range to provide sharp landscape pictures, and to maximize shutter speed in the telephoto range to minimize camera shake and blurred images. When the shutter speed falls below an acceptable limit for the camera to be hand held, the camera-shake warning appears in the lower left corner of the monitors (p. 31).

PROGRAM SHIFT

 

Although exposure calculations can be left to the

2

camera, photographers can still have control over

 

the final exposure with the program-shift function. As

 

described in the basic recording operation (p. 31),

 

press the shutter-release button partway down (1)

 

until the shutter speed and aperture value are

 

displayed. The control dial (2) can then be used to

 

shift the shutter speed and aperture combination;

 

each combination will give the optimum exposure.

 

The built-in flash cannot be used with program shift. The camera gives priority to the flash exposure; once the flash is raised, any changes made with the program shift will be canceled.
