The world of double exposure photography.

A brief history of double exposure.

Nowadays, you can easily create double exposure photographs with digital editing software, but in the past it was more complicated. “In the old days, double exposures were made by shooting an image onto a piece of film,” experienced photographer and teacher Ben Long explains. “Rather than replacing that piece of film or winding the film forward, you would take another exposure so it would be superimposed in the camera. That was a special effect then and was a wild, surreal thing for people to see.”

Multiple exposure photography was one of the earliest instances of special effects in photos. It was an opportunity to create something that couldn’t be seen with the naked human eye. People today are accustomed to altered images, so that novelty has worn off. But double exposures still offer an opportunity to push your creative limits and craft unique and meaningful images. They often result in rather abstract images, making them a great tool for understanding composition.

Learning to experiment with film.

To achieve a great double exposure, it’s important to get familiar with the process of making one with film photography. There are two main ways to accomplish a double exposure photo with film: in-camera or in the darkroom.

In the camera.

When you attempt an in-camera double exposure, you take two exposures on one piece of film. Depending on your film camera, you may need to wind the film backwards before the second shot if it automatically moves forward a frame after an exposure is taken. 

“You have to assume that when you’re doing a double exposure, it’s not going to work straightaway and you’re going to have to fiddle with it a lot.”

When attempting in-camera double exposures, you must stack your exposures. The light from your second exposure will continue to affect and darken your first exposure, so keep that in mind when setting your aperture and shutter speed. To avoid blowing out the final image, you should underexpose both shots. This is a tricky process. “Assume that when you’re doing a double exposure, it’s not going to work straightaway,” Long advises. “You’ll have to fiddle with it a lot.” Planning ahead is a huge part of double exposure success. Take the time to visualise your final image and pay attention to all the details.

Take several similar double exposure images on the same roll of film, so you can find one that works. “You don’t know what you’ve got until you develop the film,” photographer Shawn Ingersoll says.

In the darkroom.

If you’re attempting a double exposure in the darkroom, the process is a bit different. You’ll be exposing your light-sensitive paper multiple times in the enlarger (a specialised transparency projector used to project light through your photographic negative). This approach is a bit easier than in-camera, as you can use regularly shot and developed film negatives and you can position and angle the negatives in your enlarger. This added flexibility lets you experiment with the opacity of each layer by adjusting the amount of light you expose your sensitive paper to. Your first negative may need more time exposed in the enlarger, while your second negative may need only a few seconds.

Getting a double exposure in the darkroom right the first time is difficult, so patience is key. Long suggests that beginners “stick with black and white to begin with and learn the mechanism of your camera. Start with very simple situations. Try to find as empty a space as you can and put an element in it. Then combine that with another empty space and an element somewhere else. You’ll start to understand how that exposure builds up across your finished composite.” Experimenting with shadow and light is a great way to gain experience with composition in double exposure, whether you’re attempting it in-camera or in the darkroom.

The ease of digital double exposures.

With digital photography and editing software, double exposures are easier to achieve. “You can execute a shot so much more effectively now than when you were trying to double expose in the camera,” experienced photographer Carli Davidson says, “especially with images that are taken at different times or in different spaces.”

While some digital cameras have double exposure settings, the settings and tools vary depending on the brand and may not be in older cameras at all. The flexibility of editing software is where photographers and artists can really push the creative limits of double exposures. Ingersoll notes that you can “take two digital photos and lay them on top of each other. Through blending modes, transparencies and masking you can create a double exposed image.”
