How Does a Film Camera Work?
A Frenchman named Louis Lumiere is frequently recognized for inventing the first motion picture camera. In 1895, he invented the “Cinematographe” – a portable motion-picture camera, projector and film processing device, all in one invention. Motion pictures started to become very popular after the introduction of Cinematographe. Of course it didn’t stop there. The technological era produced various and more sophisticated equipment for the movie industry. Movie cameras have significantly evolved for the last century. But how does a film camera work? Read on the rest of this article and see for yourself…
A film or movie camera works by capturing a series of images. This is in contrast with still cameras that take a snapshot at a time. These series of images is called a “frame” and is achieved by using a sporadic mechanism. The frames are then replayed in a movie projector at a certain speed, known as “frame rate” (the number of frames by second). So actually, the film camera and your eyes and brain are responsible for creating the illusion of motion by merging the individual pictures. Commercial films like those produced in Hollywood uses the standardized frame rate of 24 frames per second while the standard width 35 millimeter. Other film formats that are also widely used include PAL, plays at 25 frames per second and NTSC (common in Japan and North America) at 29.97 frames/s. People in the movie industry find rendering from one format to another as one of the technical difficulties they have to face.
Majority of film cameras in the market do not capture the sound internally. The sound is record independently using a precision audio device. This setup is referred to as “double-system”. There is also the so-called single-system. These are new film cameras that have either an optical or magnetic recording apparatus inside. If you have seen those clapper boards in film production with the guy holding it and yelling these words “Title of the movie take 3 action”, they not jut simple boards. Aside from the fact that it normally starts a take it used as a reference point in synchronizing the picture with the sound. Furthermore, it allows scene and take numbers or any other important details to be included on the film itself. Currently, the most frequently applied system is unique identifier digits displayed on the border of the film. This whole process is accompanied by a computer editing system. Every film stock manufacturer has its own name for such identification system, Kodak call their version as KeyCode. There are cameras as well that have low-accuracy film systems. They are some dubbed as “non-sync” or MOS. MOS cameras are used in for second-unit work and other jobs that do not require standard filming speed. The most widely used 35 mm cameras today are Arriflex, Moviecam and Panavision versions. PhotoSonics is used in high speed filmmaking.

How To Make Your Own 16mm Black and White Film Like They Do In An Expensive Film School
New York Film Academy and NYU Film School charge students $30,000 to $40,000 a year for their programs. But most people don't realize that the actual filmmaking exercises done in these schools are very primitive and can be replicated very simply. NYU's "Sight and Sound: Film" course, a 2nd year Fundamentals Course costs about $7,000 in tuition. New York Film Academy's year long filmmaking program costs about $30,000.
In each of these courses, students make about 5 to 6 black and white reversal 16mm films. These are the kinds of movies you expect to see in a film school. Black and white, no sound. As a learning exercise, these movies actual do more damage than good because the techniques used are so out of sync with how things are actually done on a real movie set. Certainly, one need not spend this much in tuition to make movies like these to work with this level of equipment.
The camera used by these schools is the ArriFlex-S. This camera was invented in 1952. It became very popular in the 1960s, the heyday of 16mm film news shooting. However, nobody in the film business uses this camera anymore: except for film students. The camera is "non sync" meaning that you cannot shoot characters speaking dialogue; the film will not keep the same rate as the recording tape and the dialog starts to go out of sync with the mouths of the actors as they move.
Arrifliex-S cameras, where available, rent for about $150 a day. There are two rental houses in New York you can go to instead of paying thousands in tuition. Go to Hit and Run Productions in Brooklyn http://www.hitandrunproductions.com. Or Cinema Astoria Queens in http://www.cinema-astoria.com. Then go to B and H Photo and Video on 9th Avenue and 39th Street in Manhattan. Ask them for Tri-X or Plus-X Reversal Film. While you're at B & H also pick up a cheap "light meter".
Reversal film is like slide film. The image goes right on the film itself. It's the cheapest film you can shoot on which is why film schools like it. When you go to the camera rental house you just ask them how to load the film. They will show you in about 5 minutes. You can also ask them how to operate the camera and if you can rent some lights. You can get some film lights for about $50 a day.
When shooting, you simply point the light meter at your subject. You punch in the speed of your film (Tri-X is 400 and Plus -X is 200) and it will tell you what "f stop" to put your camera at. The f stop is just a little ring around the lens that lets in more or less light.
It's so simple. Basically, the brighter it is outside, the narrower the f stop needs to be. If it's really dark, then the f stop has to be completely open. The light meter does it all for you.
Then once you are done shooting you go to http://www.colorlab.com. Give them your film they will develop it for you and put it on a mini dv tape.
Then you can edit it on your mac.
If you can't get to New York simple google the following. "Arriflex-S camera rental" or "Bolex camera rental". You can also mail order the Reversal Film from B & H and also mail film into colorlab or find a lab near you.
Or you can skip this exercise altogether and make some movies with sound and color!
