[Visual Basic] Public ReadOnly Property
ExposureBiasValue1 As Integer
[C#] public int ExposureBiasValue1 {get;}
Property Value
ExposureBiasValue0 is the numerator for the exposure bias value
ExposureBiasValue1 is the denominator for the exposure bias value
The exposure bias value (unit is the APEX value) = ExposureBiasValue0 / ExposureBiasValue1
Ordinarily exposure bias is given in the range from -99.99 to 99.99
*APEX is the Additive System of Photographic Exposure, a standard unit for expressing exposure.
Explanation
The property value can be retrieved by executing the File.GetImageFileType or the File.GetImageFileTypeFromRawData method.
