Eastman and Kodak Cinematography Films «Black and White» First - Film Negatives

Eastman XT Negative Film.

Negative film, fine-grained, slow sensitivity, used for filming in the camera, as a negative film, to print copies of it for back projection, and is suitable for external photography in general.

Eastman Plus X Negative Film.

A medium-sensitivity, fine-grained negative film that is suitable for indoor or outdoor filming if the light strength is medium. Therefore, it is frequently used for most cinematic production purposes.

Eastman Double-X Negative Film.

A negative film is suitable for most purposes of cinematic production, and despite its speed of sensitivity, it is fine-grained in relation to the speed of sensitivity it has reached. It is used in both indoor and outdoor photography in low light conditions: due to its fast sensitivity, it saves a lot of the optical energy consumed when photographing in artificial light, and it allows narrowing the aperture of the diaphragm, thus increasing the depth of field without increasing the level of illumination.

Eastman 4X Negative Film.

Negative film is very sensitive and has medium grains. It is particularly suitable for filming newsreels, whether externally or internally, in poor light conditions. By increasing the depth of field very much without having to raise the level of lighting.

Eastman R.P. Negative Film

16 mm negative film used for filming with the camera, either outside or inside the studio. It is specially suitable for television filming, educational, industrial or sports purposes. It was specially prepared for very fast display in a device using a theme and installed together by the Monobat Type developer method, and it can also be shown by the usual display methods. Eastman Viscomat Processor.

Second: Reversal films

Kodak plus X Reversal Film.

Reversal panchromatic film with fast sensitivity is suitable for external or internal photography, if a suitable amount of light is available. And when treated with a reversal display method, it leads to positive images with an acceptable degree of contrast and clearly fine grains.

Note: The positive film is suitable for viewing directly on the projector or for duplication. It is also possible to use this reversal film as a negative film if you follow the “black and white” negative method. However, this method leads to a decrease in the speed of sensitivity and a slight increase in the size of the particles.

Or in weak light or at the end of the day.

Note: The same observation of the previous film applies to this flag as well.

Kodak 4X Reversal Film.

A new, highly sensitive, digital film with excellent grain and sharpness properties. He made improvements to the anti-halo layer. It is only used as a reversal film, as it differs in that from the previous two films. It is possible to double the effective sensitivity speed if the exposure time is increased in the first exposure solution, but this is at the expense of quality.
