Many amateur analogue photographers feel very daunted by double exposures. Yes, we have all tried, on purpose or accidentally, to shoot these impressive magical images. But many budding photographers are left with blown out, mediocre images.
With the cost of film very few will use an entire roll or two to experiment, document and test different techniques and ideas.
Here are a couple of tips to get you going.
Firstly, you have to think about it slightly technically. Your film is designed to be able to handle a certain amount of light for correct exposure. Because you are exposing the film twice or more you’ll have better results in lower lighting conditions. If your camera has f-stop settings (or general lighting settings like most of the Lomo’s do), you can get more detail if underexpose by 1 stop.
Try and shoot one darker and one lighter image to compose your double exposure. Shadows on one exposure will allow the details to show through from the second exposure. When composing your double exposure remember to keep a mental note and line up shadows and highlights. If you are a bit forgetful, make a little sketch in a notebook. This is also a clever way to remember what you shot if you first want to shoot the entire roll wind it back, and reshoot later at a completely different location.
Also remember there are no rules. Try only advancing your film in little sections, not the full frame, to create a storyline. You can also turn your camera upside down or sideways. Or shoot an entire roll and swop with a friend.
Anything goes as long as you keep the amount of light and composition in mind.
So, just do it. Twice.
