Copyright metadata for composite images
Hello,
I've googled and searched the forums, but can't find an answer, so I'm looking for some pointers.
Recently I’ve been creating assets for my website, some of which are stock, or stock with a minimal crop/compression - copyright and attribution for those images is relatively straightforward, I've just been referencing the Adobe Stock ID or equivalent from other platforms and giving attribution as necessary.
For composite images where I’ve used multiple stock images to create an original work, is there a guideline somewhere for how to credit the source images? I'm assuming I should be doing this in the IPTC metadata somehow?
Here's an example hosted on my cloudinary, the original photos are all from Adobe Stock, the composition, graident, etc are mine.
