How does one photograph themselves to be transparent without doing a double exposure you ask? It's simple! Continue reading and find out how!
Yourself as the model
Think about where you want to set up your self-portrait. It is important to do a little bit of planning. Just a little bit. You need to know where you’re going to put the camera, how long your overall exposure will be, and where you want to be in the shot. Will you be able to use a tripod where you want to shoot or will there be a stable surface for you to place your pinhole camera on? It is a poor ghost self-portrait if you don’t make it into your own shot. Or is it? That is another topic entirely. However, if you’re invisible people won’t be seeing through you. They just won’t SEE you.
Let’s Get Shooting!
Set up your shot and release the shutter. Since you’ve already determined (or guessed) your exposure time, you’re ready to do some math. For the first part of the exposure give it at least 1/4 of the time. *In a 60 second exposure, that’s 15 seconds.
Resist all temptation to touch the camera, close the shutter, or look through the viewfinder (ie. Holga 120PC). You will undoubtedly touch it and cause camera shake. Walk in front of your camera to pose, to smile, or to stand there naked. Whatever. *Do this for the next 1/4 amount of the exposure time; 15 more seconds.
Walk away. Do not touch your camera until you have finished your exposure; remaining *30 seconds. Close the shutter. Develop normally.
The longer you stay in front of the camera the more solidity you will be on film; less time, less solid.
*Disclaimer: Exposure time varies. This is just a guess on my part. You know your pinhole best and use your own experiences to base your exposure times accordingly.
