Movies have more information.

The size of professional film is 36 mm× 24 mm.

The photosensitive element above is silver halide particles, and the size of silver halide particles varies with different manufacturing processes. The diameter of silver halide particle pile of professional film is less than 5μm, which means that the resolution of a single film is greater than 7200×4800.

At present, the most widely used digital camera is 4K, with a resolution of about 4096×2400.

Moreover, because the color and brightness recorded digitally are used, the color depth and brightness are limited, and the sensitivity of silver halide particles changes linearly, so the film is more delicate and the color reproduction is more realistic.

Finally, the recording format of digital camera is compressed, and the image quality is lost when compressed, which is not the case with film.

To sum up, there are many recording elements in film cameras, but the high price and the problem of storage and distribution make the film slowly come to an end. With the further development of technology, digital movies will surpass movies in quality and ease of use.
