The idea ~ Experiment with pinhole photography by going back to the basics and photographing without a lens.
What is pinhole photography? Photos taken with a pinhole camera.
What is a pinhole camera? A pinhole camera is a simple camera without a lens and with a single small aperture – effectively a light-proof box with a small hole in one side. Wikipedia
Here is a great pinhole photo by Katie Cooke. Notice the camera recorded the many expressions,
and positions in a ghost like manner. There is sharpness, and also softness. Katie Cooke states on
her blog that using an empty box with no mechanics or lens, my photography is a slow, quiet conversation between camera and subject. Well put!
You can make your own pinhole camera from a cereal box, or use something more high tech like a laser made pinhole lens cap for a DSLR. The process is both simple and complicated. It is very experimental, and involves some math. Pinhole photography differs because it creates extreme depth of field but yet the photos have a soft, ethereal effect. There are many factors to consider such as pinhole diameter, focal length, film speed, and shooting conditions. Each pinhole camera can be different based on those factors. To estimate exposure, you must know your f-stop. The f-stop of a pinhole camera equals the focal length ( distance from the pinhole to the film) divided by the pinhole diameter, so fl / pd = f-stop. To simplify things I found this calculator online. I can't wait to get started!
