A77 EXIF Tags -- specifically ExposureProgram has three values

mbiggs — Mon, 20 Feb 2017 11:36:47 GMT

I want to decode the EXIF tags to tell me what the PASM etc value is used on the mode wheel.

Running Phil Harvey's exiftool like this ($ exiftool -s ExposureProgram) ALWAYS returns "Program AE", irrespective of the actual wheel position.

Running exiftool like this captures all the tags in a big text file:

$ exiftool -u -U -v JPGFILENAME.JPG > bigtextfile.txt

Looking up the tag ExposureProgram gives three different values:

1. | + [ExifIFD directory with 37 entries]
| | 2) ExposureProgram = 2

3. | | | 74) Tag2010b (SubDirectory) -->

| | | | ExposureProgram = 0

I assume |I can infer the PASM mode from these three tags....but I have no idea how to do so,

Any ideas anyone? Thanks in advance.
