An exclusive license grants you, the client, the sole use of delivered photos within the contract terms. While I retain copyright, you are the only person, aside from me, with the right to use the photos. This applies to images with identifying features. A non-exclusive license allows client use within the contract terms, but I can sell the same photos to others and use them for self-promotion. This applies to general photos without identifying features. Regardless, we prioritise respectful and ethical practices, seeking permission for personal use beyond the stated contract rights.
