Using handmade camera...
The pinhole camera has a very small hole. To record pictures with it, mainly use the bright sunlight. The exposure time, ie the time we left the light entering the camera, is determined mainly due to climatic conditions (open sky, cloudy, etc.), which affect the intensity of light, and the hole size.
In the dark, load photo paper inside the camera, holding it on the wall contrary to the hole. The small hole and low light sensitivity of photographic paper, forcing the user to leave the camera open for several seconds, which makes it impossible to hold the camera in hand, as if this move the image will be blurred (unsharp). To avoid this the apparatus must be supported on any surface and stay still during photo capture. Gently pull open the door of black paper and expose the hole light, counting the time back and close it when finished. If you have no clock, count "alligators" or any word of three syllables equivalent to one second.
Important : Remove the paper from the camera to reveal only inside a dark room.
With a very fine needle puncture carefully aluminum, turning the needle gently to remove burrs. On the outside , in front of the hole, do the "shutter" with black paper to cover the hole and has a hinge (a crease) in order to open and close like a window. The device has the function of controlling the entry of light inside the camera and should remain open or closed without the aid of hands (secure with clips). The camera is ready!
There is no display a pinhole camera. So we need to estimate the framework , that is, the visual range of the camera or how much she can see the scene being shot . To guide worth the following reasoning : the shorter the distance between the hole and the

Choose a can or box of durable material, with covers and well sealed incoming light. Paint or wrap it inside black. Make an opening of about 0.5 cm diameter with a stylus or nail thick on one side. This hole should be covered with foil, stuck with masking tape or insulation to not let in light.
