This property relates to the exposure bias. This is the numerator.

[C++Builder]   imagekitcontrolname->FileIO->Exif->ExposureBiasValue0[ = int ]
[Delphi]   imagekitcontrolname.FileIO.Exif.ExposureBiasValue0[ = Integer ]

Reference

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 set or retrieved by executing the FileIO.GetImageFileType or the FileIO.GetImageFileTypeMem methods.

The property value is derived from the image tags related to the picture taking conditions.

Setting this value

This value can be set at runtime.

Retrieving this value

This value can be retrieved at run-time.

[Differences from the ImageKit7 ActiveX]

In the IK7 this was a read only property. It can now be set.
