Camera Obscura Takeover

Definition of camera obscura : a darkened enclosure in which images of outside objects are projected through a small aperture or lens onto a facing surface.

How we did it ?

Step 1. find a suitable room which you can black out, but there is still a window so you can make an aperture.

Step 2. black out the room, covering the window with black card cut a small circle about the size of a Vaseline tin. And a little paper flap to cover the hole, but will be able to attach back to uncover the hole.

Step 3.turn the lights out, and uncover the aperture(hole). the light from outside will then project the objects from outside onto the walls. Remember that the images projected onto the walls will be back to front, so what will be on the left if you where looking out the window will be projected onto the right and visa versa.

Exposing your image

Step 4.Cover up your aperture, so that you don't expose your paper before its ready. turn off the lights

Step 5.Tape up your paper to your selected position, depending on how much light there is depends on how long you should expose your paper for, so the less the light the longer you expose the paper for, the more light the less you expose the paper for.

Step 6. in our case we exposed our paper for 2 mins, so lift the paper flap from over the aperture for two minutes.and cover back up.

Step 7.once the exposure is taken down and placed in a lightproof bag. Take to a dark room, and go through the process- i'm not going to go into that stage atm, but i'm sure i will do over the next couple of weeks :)
Unfortunately the quality of this image int great as i only had my phone on me, our exposure is the one on the right, with the 4 pieces, can you tell what it is ?..
I hope you've found this post interesting, and that it has made you want to try your own! its not hard and would only take you about an hour once you've got the materials you need!
