tagWPD_EXPOSURE_PROGRAM_MODES enumeration

Description

The WPD_EXPOSURE_PROGRAM_MODES enumeration type describes an exposure mode to use when capturing images with a device.

Constants

`WPD_EXPOSURE_PROGRAM_MODE_UNDEFINED`

The exposure mode has not been specified.

`WPD_EXPOSURE_PROGRAM_MODE_MANUAL`

The application should specify all exposure settings.

`WPD_EXPOSURE_PROGRAM_MODE_AUTO`

Use a device-defined automatic exposure mode.

`WPD_EXPOSURE_PROGRAM_MODE_APERTURE_PRIORITY`

An automated exposure mode that indicates that the lens aperture value should remain fixed, but shutter speed should be determined by the device.

`WPD_EXPOSURE_PROGRAM_MODE_SHUTTER_PRIORITY`

An automated exposure mode that indicates that the shutter speed should remain fixed, but that lens aperture should be determined by the device.

`WPD_EXPOSURE_PROGRAM_MODE_CREATIVE`

An automated exposure mode that tries to maximize the depth of field.

`WPD_EXPOSURE_PROGRAM_MODE_ACTION`

An automated exposure mode that tries to maximize the shutter speed.

`WPD_EXPOSURE_PROGRAM_MODE_PORTRAIT`

An automated exposure mode that specifies a relatively shallow depth of field.

Remarks

Indicates the exposure program mode of the device. This enumeration is used by the WPD_STILL_IMAGE_EXPOSURE_PROGRAM_MODE property.
