ELI5: What exactly is cinematography? Is it subjective? How do I know a film has good cinematography?
gpt
It's like photography but with movies. 

The things that make a good photograph also apply to making visually appealing movies. There are a lot of things that affect it. Lighting, setting, framing/composition, subject, how motion is captured, scene transition 

Yes it's subjective. But most people generally agree when something is good like with photos.

Edit: It's probably easier to tell if a film has poor cinematography than if it has good cinema-stop making me spell that.
