Copyright / Invasion of Privacy

I have photos of my STBX and his paramour in the bedroom of our marital home that I was forced against my will to take (life was threatened). I have no inclination to use these as blackmail or anything. However, I may want to use them as leverage for ED, etc. STBX says I can’t use them because they’re “copyrighted”. Well, I took the pictures. Doesn’t that mean that I own them and can do what I want with them? What are the repercussions to me, if any, if they were to be distributed to the paramour’s husband?

You own the photos and may do what you want with them.
