possible values
ExposureControls⁽¹⁾
<0> AUTOMATIC_MODE
Sets the mode for the exposure algorithm
CODED
<0> AUTOMATIC_MODE - Automatic Mode of Exposure which includes
computation of Relative Step
<1> COMPILED_MANUAL_MODE - Compiled Manual Mode in which
the desired exposure is given and not calculated by algorithm
<2> DIRECT_MANUAL_MODE - Mode in which the exposure
parameters are input directly and not calculated by compiler
<3> FLASHGUN_MODE - Flash Gun Mode in which the exposure
parameters are set to fixed values
