The double exposure technique , also called overprinting, is a very old photographic technique. As old in any case as the film photography from which it came. Originally, the first cameras did not have mechanisms allowing the film to advance. It was therefore common for the photographer to voluntarily (or unintentionally) obtain images superimposed on different scenes he had photographed.
How to do ?
The practice of this technique is very simple. What is less is finding the right subject (s) and being able to frame them in such a way as to obtain results that are pleasing to the eye or aesthetically interesting. I’m just describing you how you do it with your camera, whether it’s film or digital.
Before you start, make sure that the device you want to use has a small button to disengage the film advance mechanism. Usually it is located under the device. When activated, it reloads the camera for a new photo without advancing the film. After loading a film into your device and taking your first photo as with any other film shot, press this little button under the device and at the same time reload to take a photo again. Frame for the second exposure of the current frame. For the rest, you have the choice, take single photos or follow the same procedure for new double exposures. You will see the result when you have developed.
It’s a bit easier! Or at least faster since you don’t have to wait for development to get an idea of the result of your creation. To find the multiple exposure shooting mode, you must enter the menu. For Nikon, you will find it in the “Shooting Mode” menu, in the “Overlay” submenu. You need to activate it. You have the choice of two or three successive photos and if it is for a single photo or for a series. Once activated, the two or three photos you take will become one.
