The film Camera
What is a film camera?
The word "camera" comes from "camera obscura" which in Latin means "dark chamber". The camera was not created by one man, but more as created by many men over a long period of time. I'll go more into that later though. What a film camera is, is a camera that takes a roll of film to see the images instead of a computer disk. Film is a sheet of plastic coated with a combination of light-sensitive silver halide salts, with lots of crystal sizes that determine the resolution, contrast, and sensitivity of the film. Cameras also have a lens on them to help the image focus and to let more light in.
Most Film cameras consist of a a opening to let light in at one end. This is how the film works. Then the light comes in brightly the light sensitive salts stamp the image seen on the lens into the film. Most cameras have the lens on the front of the camera so it focuses on the image better. Today though most people have a Digital camera, which just saves the image to a SD card.
The making of the Film Camera
The Film Camera we use today is much different than the first one. Over 10 people have contributed major contributions to the Film Camera throughout the history of it.
- A Greek mathematician named Anthemius of Tralles used a dark box with a hole for light in one of his experiments.
- Ibn al-Haytharn, a Arabic scientist, described the dark box in his book titled "The book of Optics, which was written in the time period of 1015-1021.
- Roger Bacon, a Scientist-monk, also studied the dark box.
- The actual title of "Camera Obscura" was given by a mathematician and astronomer named Johannes Kepler in his Ad Vitellionem Paralipomena in 1604. He later added a lens to the camera.
- Robert Boyle, an English scientist, and his assistant, developed a portable Camera in the 1660's.
- The first small and portable camera was made by Johann Zahn in 1685. The only problem was that there was no way to keep the images, other than tracing them.
- In 1724 Johann Heinrich Schultz discovered that a chalk and silver mixture darkens when exposed to light. Photography was built on these discoveries.
- The early cameras were nearly identical to Johann Zahn's, except that they used a sliding box for focusing.
- The first permanent photograph was taken by Joseph Nicephore Niepce in 1826 by using a sliding box camera made by Vincent and Charles Chevalier in Paris.
- The first color photograph was taken by James Clerk Maxwell, a Scottish physicist in 1861.
Why aren't Film Camera's used very much anymore?
Film camera's are not used very much anymore because the film simply costs too much. It is simpler to buy a Digital Camera for 100 dollars that will be incredibly easy to use and will never cost you for film, than use a more expensive film camera, which every 50 or so pictures, you will need to spend at least $5 on more film. The film camera isn't completely unused. Many people do still use them, but ever since the Digital camera, they aren't used as much.
What people are forgetting though are memories. It's always nice to sit down and look at old photographs with your family. It is much nicer to pull out a photo album and just look at the pictures, than have to bring a computer with you if you want to see them. Another thing is that if your computer gets a virus or crashes, all your pictures are gone unless you have transferred your pictures to discs.
