Hi All,
I have an existing application that uses node-exif https://www.npmjs.com/package/exif (https://www.npmjs.com/package/exif).
I am trying to use the above but came across the fact that I can't see all tags that are available using the regular exiftool when I look at the same image metadata.
For example, using exiftool to look at Sony's "MeteringMode" I get the value "Multi-segment" but the same tag in node-exif yields the number "5". But looking here https://exiftool.org/TagNames/Sony.html (https://exiftool.org/TagNames/Sony.html) for Sony's tags documentation, MeteringMode is an int8u value where the value "1" corresponds to "Multi-segment".
Similar confusions happen for other tags like "WhiteBalance".
Aside from this, some tags simply do not appear at all in node-exif, like "Quality" or "HDR".
Would anyone have a pointer on resolving such issues?
Attached are examples files from the same image.
Tnx !
Sounds like it might be FAQ #3 (https://exiftool.org/faq.html#Q3). There may be duplicate tags in different groups. Make sure you see all tags with the -a (-duplicates) option (https://exiftool.org/exiftool_pod.html#a---a--duplicates---duplicates) and the groups they belong to with the -G (-groupNames) option (https://exiftool.org/exiftool_pod.html#G-NUM-:NUM...--groupNames).
Using WhiteBalance as an example, in my NEF file there are two entries. Looking at the human readable output (printConv in exiftool terms)
[Nikon] WhiteBalance : Auto
[ExifIFD] WhiteBalance : Auto
But looking at the raw values with the -n (--printConv) option (https://exiftool.org/exiftool_pod.html#n---printConv)
[Nikon] WhiteBalance : AUTO
[ExifIFD] WhiteBalance : 0
Thank you StarGeek !
I get:
user@dell:~/Desktop$ exiftool -a -n -G ~/Desktop/image.jpeg | grep White
[EXIF] White Balance : 1
[MakerNotes] White Balance Fine Tune : 0
[MakerNotes] White Balance : 16
[MakerNotes] White Balance : 5
yet there is no "WhiteBalance" with the value of 1 here https://exiftool.org/TagNames/Sony.html#WhiteBalanceSetting
You would look for the EXIF:WhiteBalance entry on the EXIF tags page (https://exiftool.org/TagNames/EXIF.html), not the Sony page.
Excellent Thank You
