| The camera obscura
project was initiated to show that images can form without the
aid of a lens using the same principles of a pinhole camera, but on
a much larger scale. Almost everyone has probably seen or used
a pinhole device at some point in their study of science. It
is, however, a very exhilarating experience to be standing INSIDE of
a camera and seeing the image form! What was very intriguing to our
team was the simplicity of the
concept, the high impact images, and the chance to examine the
interface of camera history and today's technology .
After the camera was
created we were able to observe that the sharpness of the images
changed noticeably as a function of the size of the opening or
aperture. The image intensity also changed dramatically with
the smallest apertures producing low intensity images.
While we expected to make
these qualitative observations, we wondered if we could determine
the resolution of each aperture through the use of the image
software tool, ImageJ. The web presented is an overview of our
project, the results thus far, and links to Rochester Institute of
Technology's Center for Imaging Science.
