There is a general category of keys that have more than 1 location in APS file, but only 1 location
in the EXIF file format. The CaptureConditions.Flash... keys fit into this category. PMT needs to
be fixed to deal with these keys, because currently, there exists a single key to handle the EXIF,
and a couple of keys to handle APS. This is incorrect.
For example, PMT specifies the key CaptureConditions.Flash.Flash, which conceptually would map
to one tag location in an EXIF file. But it also has the keys CaptureConditions.Flash.Fired and
CaptureConditions.Flash.Return, which maps to the same logical information as EXIF, but has two
physically separate location in an APS file. In other words, two logical fields are combined into 1
bitmask in EXIF, but exist seperately in APS.
The keys in this catagory are:
CaptureConditions.Flash.Flash
CaptureConditions.Flash.Fired
CaptureConditions.Flash.Return
CaptureConditions.Flash.Energy
