DJICameraExposureParameters

struct {}

This class contains current values for some camera parameters related to exposure, which determines how sensitive the picture is to light and depends on the balance of the ISO value, the shutter speed, and the aperture value. When the camera is in different exposure modes, different parameters are automatically changed by the camera to either get the correct exposure (in Program, Shutter Priority and Aperture Priority modes), or report back the current exposure (in Manual mode). The current values of these parameters used by the camera are contained in this class.

  • Camera aperture value. A larger aperture results in a higher exposure and shallower depth of field.

  • Camera shutter speed. A slower shutter speed results in a higher exposure, but more blurring in areas of the scene that are moving.

  • iso

    Camera ISO. A higher ISO results in a higher exposure, and more noise in the resulting image.

    NSUInteger iso

  • Returns the camera’s current exposure compensation. In Program, Aperture Priority and Shutter Priority modes, the exposure compensation value changes the exposure target the camera is using to calculate correct exposure and is set by the user. For example, Aperture Priority mode indicates that the priority is to maintain the aperture setting and adjusting the exposure by varying the ISO and shutter speed. In Manual mode, this value is reported from the camera and reports how much the exposure needs to be compensated for to get to what the camera thinks is the correct exposure. In Manual mode, the range of exposure compensation reported by the camera is -2.0 EV to 2.0 EV. In Program, Aperture Priority and Shutter Priority modes, the range of exposure compensation is -3.0 EV to + 3.0 EV. For the Z30 camera in manual mode, exposureCompensation is not used and the value is always DJICameraExposureCompensationN00.
