Pinhole Camera Worksheet

1. Camera obscura is a darkened box, in this case a can, that consists of an aperture, a shutter, and it must be light tight. The aperture is for projecting the the image of an external object onto the light sensitive paper strip inside. It is very important in the development of photography.

2. A pinhole camera consists of an aperture and a shutter and is light tight, so that no light can enter it. There is no lens on a pinhole camera.

3. The three most important things that all cameras have in common is an aperture, a shutter, and a light tight surrounding.

4. The two parts of the camera that allow light to enter in are the aperture and the shutter. The shutter covers over the aperture, but allows the light into the camera when lifted to reveal the aperture.

5. To test the pinhole camera for "light leaks" you must take light sensitive photo paper and put it inside the can directly across from the aperture. Then you must seal your can so that no light gets in. After taking it outside for a few second in the light, you must come back in and go straight for the chemicals. Once the paper goes through the developer, the stop bath, and the fixer, if it is white then there were no light leaks, if the paper is black, light got into the camera. To fix this, you must make sure that there is black paper covering your entire can and the lid is securely covered as well, make sure the shutter is completely covering the aperture as well. There should be no light what so ever getting into the can.

6. Camera shake is when the camera moves while you are trying to capture an image and it results in the photo being blurry. To prevent this, you need to make an equal distance between your subject and your camera and set it down on  a stool or table that way there will be no movement. If the camera and subject don't move, there will be no camera shake.

7. The developer is the first step in the darkroom and it brings out the latent image of the photo sensitive sheet.

8. The stop bath stops happens after the developer and it stops the developing process.

9. The fixer is the last step of the process and it stabilizes the image. This will remove any excess chemicals that is still on the photo paper.

10. It is important to agitate the chemicals when printing because the chemicals must cover the entire photo strip. If you do not cover the entire photo strip, there will be blotches on the photo strip and you won't be able to see the full image.

11. To prevent prints from sticking together, you must keep agitating the chemicals so the strips are moving around and use the prongs to move them around if they become too close together.

12. We wash prints because it is important to wash off any excess and unwanted processing chemicals. It may cause destruction of the image if not washed.
