Retrieve all EXIF data from image

1

Hello, I have images received from client that has “keyword” meta data stored in it. I’m trying to use Kirby’s $img->exif()->data() to retrieve this data. While I’m seeing almost all of the data that I can see using Photoshop’s File Info panel, like “ImageDescription”, “Document Title”, “Copyright” etc, I’m unable to see the piece of data that I’m after… the keyword data. As is shown in the photoshop panel the data exists.

So I’m wondering if there’s another property of the image I need to be looking at besides exif?

Thank you

$img->exif()->data()

Thanks for the response. Here’s what is outputted when I run the following command. Lots of info is there. But no ‘keyword’ info is there.

$exif = $img->exif()->data(); print_r($exif);

From googling around, It looks like the Keywords are part of something driven by Adobe to extend the base set of Exif data properties. Since its probably not part of the standard spec, and potentially something copywrited by Adobe, I think your probably out of luck.
