Who owns the copyright of the 360 photos?

We've made the terms favourable to the photographer in terms of copyright, and to the buyer in terms of usefulness. The Buyer (customer) can do a lot with the photos including creating derivative works. But the copyright ownership remains with the Seller (photographer). As per clause 5 of our Terms and conditions,

5. Unless otherwise agreed to in writing between the relevant parties, the copyright of all content created by a Seller, including any derivative works made under licence by other users such as Buyers and Viewers, remains with the Seller.
