Multiple exposure is making more than one exposure on film. Multiple exposures can create striking and impressive images. The exposures can be thematically related or can be parts of an interesting design. Many film SLR cameras have multiple exposure buttons that makes things easier. In digital format it is even more simple, open a picture in a photo editor, put the second picture on it as a layer than change the opacity of the pictures as you wish. (sum of the opacity of the pictures should be %100)

You can also use multiple exposures for showing the changing positions of a subject in the scene. While the subject is moving, you can capture it in the different parts of the frame by placing your camera on a tripod and not moving it until you are finished. To avoid the camera shake you can use a remote shutter release cable. I’m sure you saw moon drawing an arc in the picture before. If not i look something like this;

This is an example of multiple exposure. You can also apply this technique to any subject you want.

If you are using a film camera you should adjust before or the picture will be overexposed. It can take time to get familiar with the settings and find the correct ones for different conditions in multiple exposure pictures. But if you are using a digital camera you don’t have to worry about it, just take the pictures as they are single exposure pictures than put them together in an image editor.
