Exposure / capture parameters.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

iso: Option<u32>

ISO speed.

exposure_time: Option<f64>

Exposure time in seconds.

f_number: Option<f32>

Aperture as an f-number (e.g. 2.8).

focal_length: Option<f32>

Focal length in mm.

focal_length_35mm: Option<u32>

35 mm-equivalent focal length in mm (EXIF FocalLengthIn35mmFilm).

exposure_bias: Option<f32>

Exposure compensation in EV.

flash: Option<u16>

EXIF Flash tag value (bit field; bit 0 set when the flash fired).

metering_mode: Option<u16>

EXIF MeteringMode tag value.

exposure_program: Option<u16>

EXIF ExposureProgram tag value.
