Polyester is the most recent film base to have been developed.

It is made of film base dissolved in a solvent.

The film base is also thinner and more transparent, making inspection of the negative easier.

Triacetate is typically used for the creation of fibres and film base.

Many are not 100% conclusive, and it is best to use a selection of these to positively verify a film base.

It is important to avoid stray printing light exposing the film base of film.

However, the celluloid film base produced by this means was still considered too stiff for the needs of motion picture photography.

As the degradation progresses the film base becomes brittle and shrinks.

The three emulsions were on unusually thin film bases.

It consisted of (essentially) a black-and-white film base and three-color filter layer.

About half the material released was methylene chloride, a toxic solvent used to make film base.

The polyester film base is often recycled.

All film stocks were manufactured on a nitrate film base, which is highly flammable.

By 1896 the new movie projector required a fully transparent film base that Blair's American operation could not supply.

The emulsion is attached to the film base with a transparent adhesive called the subbing layer.

The plastic film base becomes brittle.

There are several factors which can aid in identification of the film base of a roll of film.

The cable usually consists of a flat and flexible plastic film base, with multiple metallic conductors bonded to one surface.

The film base was dyed blue, printed with a mosaic using a resistive greasy ink and bleached.

Panchromatic emulsions on a film base were not commercially available until the 1910s and did not come into general use until much later.

Photographers who load their own cassettes can use any length of film - with thinner film base up to 45 exposures will fit.

Trucolor differed, however, in that it used a dye-coupler already built into the film base, rather than the application of chemical toner.

Much of the early cinema film made in New Zealand has been lost, as it was printed on unstable nitrate film base.

An interesting development is the direct synthesis of acetic anhydride, used to make cellulose acetate for photographic film base.

These are the main raw materials in Kodak's Estar polyester film base for graphic arts films.
