Pinhole Camera Positive Worksheet

Pinhole Camera Positive Worksheet

1. You focus the enlarger on F3.5. 

2. You know the enlarger is focused when the edges are crisp and clean and the square shadow is clear. 

3.  After focusing the enlarger you switch it to F8.

4. You write on the dull side.

5. You write you initials, f8 and the time you did it for.

6. The shiny side is the emulation side. 

7. It tests how long you should expose it to light for.

8. You make a test strip by using a strip of photo paper. You lay it on your negative on the enlarger and expose it to light at increments of 2 seconds. When it is done, you run it through the chemicals. Look at which length of time creates the best image.

9. They stay in the trays.

10. You prevent the prints from sticking together by squeegeing them after they go through the chemicals.

11. You put your prints in your binder when they're dry.

12. You should post a picture of your prints with an explanation of your process or answer the questions from the worksheet that goes along with the assignment.

1. A camera obscure is a darkened box with a convex lens or aperture for projecting the image of an external object onto a screen inside. 

2. A pinhole camera is a camera with a pinhole aperture and no lens.

3. The three things that all cameras have common are the shutter, aperture and they are light tight.

4. The aperture and shutter allow light to enter in.

5. To test the camera for light leaks you go outside with a test strip and don't do anything to the camera - don't lift the shutter to reveal the aperture. Stand outside for 10-20 seconds. You then develop the test strip. If the strip is white this shows you that no light entered the camera, if there is any black or gray then that means the camera is not light tight. If there is a light leak you need to try to cover the camera in more black paper, or use tinfoil over the cap. The aperture may also be too big.

6. A camera shake is the movement of the camera while lifting the shutter and taking a picture. To prevent camera shake place the camera on a flat and level surface.

7. The developer converts the latent image into a visible photograph. 

8. The stop bath halts the development of the film, by washing off the developing chemical or neutralizes it.

9. The fixer stabilises the image, removing the unexposed silver halide remaining on the photographic dil leaving behind the re reduced metallic silver that forms the image. 

10. It is important to agitate the chemicals when printing because this allows the photograph to develop with fewer flaws. It prevents stroking, streaking and the staining of the finished print.

11. To keep the prints from sticking together, you put them in the fish tank so the excess chemicals and water come off. Keeping them separate from one another is also another way that you can keep them separate. If they do end up touching you want to keep them emulsion side to emulsion side. 

12. We wash the prints to make them clean.
