What do you mean by multiple exposures in photography? Come in detail. Do you need a film camera?

Multiple exposures are mostly used in film cameras.

It is mainly to expose a negative for more than 2 times to present an image.

For example, when shooting sunrise or sunset, use a tripod to make multiple exposures at the same angle, so that you can present the feeling of several suns in a scene and feel the sunshine flowing in the photo.

As for digital photos, it is basically difficult to make multiple exposures in the traditional way, but through post-production.

In this way, the so-called time-lapse film has been developed.

For example, from bud to flower, take a photo of the flower every 10 minutes, and then play the photos together. You can observe the growth and withering of a flower in a few minutes.
