The Camera Obscura.
The images on the right show me , Allesiha and Nafisa making our camera obscure we had some difficulty making it by we got there in the end.
What is a Camera obscura ?
Well it is a darkened chamber in which the real image of an object is received through a small opening or lens and focused in natural color onto a facing surface rather than recorded on a film or plate.
You can make this all you need is :
- Pringles tube
- duck tape
- grase proof paper
you can make this at in comfort of your own home.
Telephoto Lens Version
I started by cutting the tube in to two different lengths so that one could fit inside the other. I placed a small piece of greaseproof paper across the end of the smaller tube and taped it to the sides tight. Then I attached a small piece of tinfoil over the end of the wider tube, taped it to the sides securely and made a tiny pin hole in the tin foil.
then I took the thinner tube placed inside the wider tube and moved it backwards and forwards noticing how the image got bigger and smaller. I adapted the camera by creating a special eye piece at one end to make sure that very little light got into the tube. The darker the tube inside, the brighter the image appeared.
