Where the 'history software agent' is coming from?

[yanivf]

Hi,
I'm newbie to EXIF but I started to understand how it works. In one of the images, the 'history software agent' is filled and I'm trying to figure out how that string is retrieved.

I saw in the EXIF tag list that there is 'software usage' tag 0x131 but when I try to pull info using this tag I get a different value.

Thanks

To retreive 'history software agent', use this command:

exiftool -historysoftwareagent FILE

where FILE is the name of your file.

If you just use this command, you will retrieve all metadata:

exiftool FILE

including HistorySoftwareAgent if it exists.
