Camera Obscura.
|
This video shows a group of people trying to make a camera obscura in an office inspired by the work of Abelardo Morell. They make the room completely dark by taping black sheets to the windows. They then cut a small hole to let in a light and an upside down image appears on the opposite wall. The reason this happens is because light travels in straight lines.

I decided to try to create a fixed lens version of camera obscura using the following materials:
Fixed Lens Version . I used only one tube, cutting a section from the end over which I taped the tinfoil. I covered the longer section with greaseproof paper before re-attaching the shorter section. I made a tiny pin hole in the tinfoil and was then able to observe an upside down image projected onto the greaseproof paper screen inside the tube (see opposite). I was really pleased with my cameras. However, the fixed lens version was very successful because I used a wider tube and the image was bright and clear,But word of advice you need light or the camera is no use. Also do not make your hole to big or it will ruin pin hole camea. |
