What is a movie stock?

Film Stock is an essential part of all film images, allowing you to capture and reproduce images using the camera. Since early experiments with celluloid film at the end of the 19th century, a film has been with a film with a constant revolution through the development and improvement of the film. Thanks to the applied technical witchcraft, the film moved from the granular black and white paintings of the original Kodak camera to the color miracles of modern shares in a little over a century.

Originally the film was built on a paper base, which made the composition of moving images an incredibly difficult process. Celloid film shares, which were flexible and less fine than paper, were heavily launched on the market, including George Eastman and Thomas Henry Blair. Despite the considerable advantages provided by a celluloid film, the early film supply was insufficient in several serious things: it was not able to process red light and had no standardized size.

were the film cameras in the first daysOften unique to its creators, which led to all kinds of variations of the size of the film used. Once the equipment has become standardized, film reserves began to be released in several typical sizes, especially in widths of 35, 16 and 8 millimeters. The thing of the film, which was portrayed in realistic color, was not solved until the beginning of the 20th century, with the invention of a panchromatic film that saw a red, blue and green layer of light.

Today, a modern film supply is much more complicated than it looks. Instead of a simple piece of dark flexible material, the typical piece of film contains several different layers of emulsions and filters. At the peak of the safety base, the anti-de-de-deepening layer is prevented, followed by layers of red, green and blue emulsions, each of which has a filter between them. The film also contains yellow, purple and cyan dyes that are released during processing to give full spectrum BAroar.

When buying film supplies for film, speed and resolution, there are two key features to be considered. The film width determines the distinction or sharpness of the image given by the film. The 8 mm film usually has the lowest resolution, while the 35 mm film is a standard form of almost all major films. The speed of the film determines how sensitive the film has light; If many night scenes are planned, a higher speed of the film may be required. However, the higher speed of the film can reduce the resolution, so the filmmakers tend to look for a happy medium in terms of resolution and speed.

Film stocks

can be quite expensive, depending on the width of the film and the length of the role used. With a 35 mm film, a 1000 ft (304.8 m) war will result in approximately 10 minutes of usable film, and usually starts at $ 500 (USD) using a film with a lower resolution such as 8 mm, will result in more time on the foot of the film and can be a wise solution for amateur or low -cost filmmakers. Some enterprising independent filmmakers decide inYnout the film supply completely by filming on digital cameras, but film cameras are still mostly considered by experts as a giant film industry.
