iso_speed_ratings |
Photosensibility (read-only) |
exposure_time |
Exposure time (reciprocal of the shutter speed; read-only). The unit is second. The upper 16 bits are the numerator, and the low 16 bits are the denominator.
|
exposure_bias_value |
Exposure compensation during photographing (read-only). The unit is APEX (EV). The upper 16 bits are the numerator, and the low 16 bits are the denominator.
|
exposure_program |
Exposure program used by the camera during photographing (read-only). 1: manual exposure 2: normal program exposure 3: iris-first exposure 4: shutter-first exposure 5: creative program (low-speed program) 6: motion program (high-speed program) 7: portrait mode 8: landscape mode |
f_number |
Aperture coefficient (read-only). The upper 16 bits are the numerator, and the low 16 bits are the denominator. |
max_aperture_value |
Maximum aperture value of the lens (read-only). The upper 16 bits are the numerator, and the low 16 bits are the denominator. |
exposure_mode |
Exposure mode (read-only) 0: automatic exposure 1: manual exposure 2: automatic exposure bracketing (AEB) |
white_balance |
White balance (read-only) 0: automatic white balance 1: manual white balance |
