In general, these are separate rights. A copyright license from the photographer covers use of the photo as a creative work; it does not automatically grant rights related to the subject’s likeness, privacy, or publicity.

So a reuser may need:

• the photographer’s permission (or a valid license such as Creative Commons), and
• the model’s permission, if the intended use requires a model release under the applicable law.

If the law provides an exception—commonly mentioned examples include some journalistic/editorial uses—then a model release may not be required, and the copyright license alone may be enough.

If you obtained a model release, that can cover the model-rights side for the uses allowed by that release. Without it, a downstream user may need to get the model’s permission separately.

Exact rules depend on jurisdiction and on how the image will be used, so this is a general explanation rather than legal advice.
