Quote from: banana123 on February 14, 2024, 10:35:47 AMFor example - one thumbnail image is at APP1 as part of the EXIF data and another image is part of APP13 as part of photoshop data?
I think they have different names.
ThumbnailImage in the EXIF group and
PhotoshopThumbnail in the Photoshop group. But I don't have PS to be able to check.
QuoteAnd another question - is there any way to get the value for each metadata field as hex / binary?
There's the
-b (
-binary) option (https://exiftool.org/exiftool_pod.html#b---b--binary---binary) to get the raw data from a tag like the thumbnails, but it won't be separated from any other tag you extract.
Adding the
-X (
-xmlFormat) option (https://exiftool.org/exiftool_pod.html#X--xmlFormat) or
-j (
-json) option (https://exiftool.org/exiftool_pod.html#j-JSONFILE--json) will give you the binary data in Base64. The
-php option (https://exiftool.org/exiftool_pod.html#php) will encode any non-printable characters in hex.
Another option would be to use something like this (taken from StackOverflow) (https://stackoverflow.com/a/56184271/3525475)
s/(.)/sprintf '%04x', ord $1/segand use the
-api Filter option (https://exiftool.org/ExifTool.html#Filter) (note that this would be global, affecting
all extracted tags)
-api "Filter=s/(.)/sprintf '%04x', ord $1/seg"or the
-p (
-printFormat) option (https://exiftool.org/exiftool_pod.html#p-FMTFILE-or-STR--printFormat) on individual tags
-p "${ThumbnailImage;s/(.)/sprintf '%04x', ord $1/seg"I haven't tested these last two, so they may require some fixing.

...unless you use the
-W (capital "W") output option with
%t (tag name) or
%c (copy number) in the file name string.
