Pinhole photography

Photography is not just an art: Scientists at Wynberg Girls’ High are exploring the science of pinhole photography. For those a little uncertain of what pinhole photography is this information from might help:

Pinhole photography is lensless photography. A tiny hole replaces the lens. Light passes through the hole; an image is formed in the camera. Pinhole images are softer – less sharp – than pictures made with a lens. The images have nearly infinite depth of field. Wide angle images remain absolutely rectilinear. On the other hand, pinhole images suffer from greater chromatic aberration (it creates “fringes” of colour along boundaries that separate dark and bright parts of the image) than pictures made with a simple lens, and they tolerate little enlargement. Exposures are long, ranging from half a second to several hours. Images are exposed on film or paper – negative or positive; black and white, or color.

Emily Danielz has been experimenting with a pinhole camera and the kind of photography that is possible.  This is usually a very difficult project to get right, but she has researched, consulted experts, put a great deal of time and energy into the project and has achieved what most others have not in the past. These photographs  show Emily Danielz with her functioning pinhole camera, taking a picture of the class. The outcome of this class photo is currently being developed but the photographs of Emily is the result of one of the photographs that she has taken with the camera. It’s a particularly fine example of this kind of photography. Well done to Emily!
