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
2. | | | 72) AFInfo (SubDirectory) -->
| | | + [BinaryData directory, 12288 bytes]
| | | | ExposureProgram = 0
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.
