How to shoot the effect in the film?

If you are pursuing the ultimate effect, you need to move the axis lens ~ the price is not low. The principle of this lens is to correct the perspective distortion in architectural photography by distorting the light path, and it can also seamlessly splice ultra-wide images.

It can also make the miniature model feel a large area, and you can't see the lens with a mirror.

Conversely, ordinary shooting scenes can also look like models.

Of course, the requirements are not high ~PS can achieve almost what you want.
