What I mean by "cinematographic metaphor" is that, instead of expressing metaphors using words, you use images that are imprinted in your mind through descriptions in a novel.
Here's what I mean:
We often say that vengeance is an empty thing. So we could have a scene describing someone drinking alcohol from a glass and drinking it all, and show that the glass is left empty like the person who consummated the vengeance. Is this a thing?
Here's what it could look like:
Matthew sat alone in the room. It was midnight. He grabbed a glass of vodka. The ice had long melted away. He drank it all, and pounded the glass onto his desk. The glass, now empty, was sitting in the middle of the desk. The upper part was now broken and reflected his twisted visage.
