Multiple images exposed onto single frame without cutting — ghosts, overlays, abstract layers built in-camera. Classic effect, no post-work needed.
You expose the same frame multiple times in succession — without changing the magazine, without cutting. Each exposure optically adds to the previous one. The result: ghost images, transparent overlays, effects that make it seem as if a second reality is shining through the first. Classic craft, not post-production. The control is entirely in your hands — and requires precise thinking before shooting.
Practically, it works like this: You set the exposure for each take anew. If you film a person twice on the same negative strip, each exposure must have about half the normal light values — otherwise, the image will be overexposed and unreadable. For three overlays, it's a third per take, respectively. Modern digital cameras often have a native multi-exposure function in the menu — you shoot the takes, and the electronics calculate the exposure values into each other. With analog film, you need the fade-in/fade-out system: you dim the iris between takes so that each new layer appears in exactly the right places.
The psychological effect is the core business: a person sits next to themselves in the same room — not through VFX, but because the camera photographed them twice. This creates a ghostly, timeless quality. Doppelgänger scenes, inner conflicts made visible, memories that waft through the image like echoes — all without editing. Caution: Any movement between takes must be choreographed. If the first person raises a hand and the second stands up, it creates confusion instead of an effect.
In the edit, you lose control. Therefore, you must think through multi-exposure completely on set: Which movements fit together? How bright will each layer be? Test Polaroids are your best friend — or the histogram function of the digital camera. A classic example: Orson Welles' Citizen Kane used the technique for psychological scenes. Today, you see it in art-house films, in music videos, everywhere where the doubling of emotion is concerned — not technical trickery, but aesthetic truth.
