I have a photo of my hand. Can I add an extra finger with AI?

@ Sure - make sure your selection encompasses the existing fingers:

Then use prompts to add digits.

This was "Five fingers outstretched"

in the future, to find the best place to post your message, use the list here, https://community.adobe.com/

p.s. i don't think the adobe website, and forums in particular, are easy to navigate, so don't spend a lot of time searching that forum list. do your best and we'll move the post (like this one has already been moved) if it helps you get responses.
