How much metadata is leaked through posts and images/videos on Nostr?

As a very big fan of anonymity, is there anything I can do to enhance my privacy other than using vpn/alias? I am aware of tor but am not familiar enough with it.

There have been a few occasions where I have wanted to post interesting pictures from travels etc but am concerned about the metadata they may have attached.

Thanks in advance for any insights.
