A re-can is a roll of film stock which was originally opened up from a factory-sealed can and loaded into a camera magazine by a clapper loader, but remained unshot and thus was unloaded back into a film can unused. A re-can will be placed in a black bag in a film can which is then sealed and identified as a re-can, as well as including the film type, emulsion number, and when it was unloaded. Identification is critical, as there may be no other way to know what exactly is inside the can. Re-cans should be sealed in either white or colored gaffer tape, depending on what (if any) color scheme is being used to identify film types; in any case, black gaffer tape should not be used, as it is considered the standard tape color used to seal exposed cans. If any of the roll has been shot, it is not considered a re-can, but rather a short end.
Film stock is an analog medium that is used for recording motion pictures or animation. It is a strip or sheet of transparent plastic film base coated on one side with a gelatin emulsion containing microscopically small light-sensitive silver halide crystals. The sizes and other characteristics of the crystals determine the sensitivity, contrast and resolution of the film. The emulsion will gradually darken if left exposed to light, but the process is too slow and incomplete to be of any practical use. Instead, a very short exposure to the image formed by a camera lens is used to produce only a very slight chemical change, proportional to the amount of light absorbed by each crystal. This creates an invisible latent image in the emulsion, which can be chemically developed into a visible photograph. In addition to visible light, all films are sensitive to X-rays and high-energy particles. Most are at least slightly sensitive to invisible ultraviolet (UV) light. Some special-purpose films are sensitive into the infrared (IR) region of the spectrum.
A film can is the light-tight container used to enclose film stock. They are typically a circular box pressed from thin sheet metal, but plastic examples are also used. Film cans are used to hold unexposed film, exposed film ready for developing and also for the distribution of completed film prints. The last of these does not require the can to be light-tight, but environmental protection and exclusion of dust makes a similar container just as useful.
A camera magazine is a light-tight chamber or pair of chambers designed to hold film and move motion picture film stock before and after it has been exposed in the camera. In most movie cameras, the magazine is a removable piece of equipment. Many still photo cameras also have removable camera magazines. A film cartridge serves the same function, but is usually not reusable.
Re-cans are considered distinct from new rolls because they may have been subject to environmental conditions since leaving their originally sealed can and are no longer under factory warranty, and are generally identified distinctly to avoid any confusion in the matter. Assuming proper storage and fast turnaround time, they are considered perfectly usable. Older re-cans or ones of uncertain provenance should be clip tested first to check their condition. Re-cans and short ends are often sold at discounts to lower budget productions by labs, larger production companies, or businesses which specialize in their sale.
In general, turnaround time (TAT) means the amount of time taken to complete a process or fulfill a request. The concept thus overlaps with lead time and can be contrasted with cycle time.

Flexography is a form of printing process which utilizes a flexible relief plate. It is essentially a modern version of letterpress which can be used for printing on almost any type of substrate, including plastic, metallic films, cellophane, and paper. It is widely used for printing on the non-porous substrates required for various types of food packaging.
Gaffer tape is a heavy cotton cloth pressure-sensitive tape with strong adhesive and tensile properties. It is widely used in theatre, photography, film and television production, and industrial staging work.
135 is photographic film in a film format used for still photography. It is a cartridge film with a film gauge of 35 mm (1.4 in), typically used for hand-held photography in 35 mm film cameras. Its engineering standard for the film is controlled by ISO 1007.
126 film is a cartridge-based film format used in still photography. It was introduced by Kodak in 1963, and is associated mainly with low-end point-and-shoot cameras, particularly Kodak's own Instamatic series of cameras.
In film and television production, B-roll, B roll, B-reel or B reel is supplemental or alternative footage intercut with the main shot. The term A-roll referring to the main footage has fallen out of usage.

Pu'er or pu-erh is a variety of fermented tea produced in the Yunnan province of China. Fermentation in the context of tea production involves microbial fermentation and oxidation of the tea leaves, after they have been dried and rolled. This process is a Chinese specialty and produces tea known as 黑茶 hēichá commonly translated as 'dark tea'. This type of tea is different from what is known as black tea in English, which in Chinese is called 红茶 hóngchá.
In a film crew there are two kinds of best boy: best boy electric and best boy grip. They are assistants to their department heads, the gaffer and the key grip, respectively. In short, the best boy acts as the foreman for his department. A woman who performs the duties of a best boy may be called best girl.
A label is a piece of paper, plastic film, cloth, metal, or other material affixed to a container or product, on which is written or printed information or symbols about the product or item. Information printed directly on a container or article can also be considered labeling.
A silo is a structure for storing bulk materials. Silos are used in agriculture to store grain or fermented feed known as silage. Silos are more commonly used for bulk storage of grain, coal, cement, carbon black, woodchips, food products and sawdust. Three types of silos are in widespread use today: tower silos, bunker silos, and bag silos.
A film base is a transparent substrate which acts as a support medium for the photosensitive emulsion that lies atop it. Despite the numerous layers and coatings associated with the emulsion layer, the base generally accounts for the vast majority of the thickness of any given film stock. Historically there have been three major types of film base in use: nitrocellulose, cellulose acetate, and polyester.
A short end is a partial roll of unexposed film stock left over during a motion picture production and kept for later use. The short end may be sold to a film dealer who will resell it to productions who are in a position to use it.
In film and television crews, the gaffer or chief lighting technician is the head electrician, responsible for the execution of the lighting plan for a production. The term "gaffer" originally related to the moving of overhead equipment to control lighting levels using a gaff. The gaffer's assistant is the best boy electric.

Kino Flo is a manufacturer of lighting equipment for use in motion pictures, television and photography. Located in Burbank, California, Kino Flo is best known for its fluorescent tube arrangements that are used for the color of film and digital video. These lights provide a relatively compact and efficient way of providing soft lighting. Compared to the original workhorse of motion picture lighting, incandescent lights, Kino Flo tubes produce less heat and fit into smaller spaces, two significant advantages that have made them popular with professionals.
