Pinhole camera worksheet

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

2.) A pinhole camera is a closed light tight chamber with a pinhole aperture and no lens.

3.) All cameras have a shutter, an aperture and are light tight.

4.) The shutter and the aperture allow light to come in.

5.) In order to test the camera for "light leaks" you go outside with a test strip inside your camera and let the camera sit still for 10-20 seconds without lifting the shutter. then you develop the test strip, if your strip is white then this shows that your camera is light tight, if the strip is black or grey it means it is not light tight. in order to fix any light leaks you may need to make your camera more secure by covering it in more black paper, another problem that can cause light leaks is if your aperture is to big.

6.) Camera shake takes place when you moves the camera while you are opening the shutter, to avoid this place the pinhole camera on a flat stable surface.

7.) The developer transfers the latent image into a visible photo.

8.) The stop bath halts the developing process by washing off the developing chemical
9.) The fixer stabilizes the image, removing the unexposed metallic on the photograph.
10.) Agitating the chemicals when printing because it causes the photo to develop with fewer flaws such as streaking and staining on the finished product.
11.) To prevent prints from sticking together by laying the pictures spaced out in the tray.
12.) We wash the prints to get all the chemicals off of the finished product.
