A double exposures is a technique which allows a photographer to combine two images into a single photo. Most often this technique is accomplished by the use of a film camera when you use a roll of film, rewind the roll, and start again. The end result is an artist, although sometimes messy looking, shot of two images made into one.
Unfortunately for some, film isn’t as popular as it used to be, and the world of photography has been shifting more and more into the digital age. What used to take hours – if not days – to develop in a photo lab now takes mere minutes – if not seconds – to upload directly onto your computer.
This doesn’t mean that the world of double exposures is a thing of the past, however. You can still create the same effect using your digital photographs. Of course it technically won’t be considered a true double exposure, but the end result can be almost identical. Here’s how it’s done:
You’ll need two photographs (or more, but the fewer the better) and a photo editing program on your computer (this article will explain using Gimp, but any will work).
Your pictures should be the same size, so trying to combine a horizontal photo with a landscape one may not work. The first step is to open one of the images that you will be combining. Then go to the file menu and choose “Open as Layers.” This will allow you to choose the other photo you will be layering, and it will place one on top of the other.
The technique is halfway done at this point, and the rest is even easier. All the way to the right of the screen there will be a “layers” box with an option for opacity. The more the slide is moved to the left, the more blended the picture will be.
This is an incredibly simple, very fast way to create the double exposure effect on digital pictures; no developing required!
