Summary
This quote suggests that a theory, just like a photograph, is meant to represent something but it is not the same as the actual thing it represents. It implies that a theory is not equivalent to an established fact, merely a representation or an interpretation of reality. Similarly, a photograph captures an image of a person, but it cannot fully capture their essence or existence. Likewise, a theory may convey an understanding or explanation, but it should not be mistaken for an absolute truth or undeniable fact.
