MeteringMode seems to be wrong

[PaulPanter]

If i use PHP with exif_read_data(), i get for some image the value 5 for MeteringMode. But with

Code Select Expand

exiftool "path/to/IMG_4667.jpg" -MeteringMode -n i get the value 3 for the same file. 5 is the correct value. Do someone have a idea, why this happens and i get the wrong value with exiftool 12.57?

Use the command in FAQ #3 as your base command so you can see all the tags with that name and the groups they belong to.

exiftool -G1 -a -s -n -MeteringMode /path/to/files/

MeteringMode can appear in several different groups, include the Makernotes from different cameras. It's quite possible that without the -a (-duplicates) option you are seeing the MeteringMode from a different group.

Ahhhhh, have found a solution. You are my hero:

exiftool "path/to/IMG_4667.jpg" -ExifIFD:MeteringMode -n
