Techniques Glossary Reversal film
A film to produces transparencies that are viewed with projected light.

COLOR REVERSAL FILM PROCESSING Color transparency film forms dyes according to a reversed silver positive; for example, a yellow dye image forms in the top emulsion that corresponds to an absence of blue in the original scene.

Reversal Film
Positive (i.e. slide) film. Film in which the original negative image is reversed during the development process to produce a positive transparent image.

Reversal film
Film or paper designed to produce a positive directly from exposure and processing, without the need of a negative.

Reversal film. Photographic film that produces a positive image (transparency/slide) upon exposure and development.
Rewind crank. A device, usually on the top of the camera, for winding film back into a cassette once it has been exposed.

Reversal Film: A type of film that produces positive images by being reversed from negative images during processing. Colour slide films are reversal films.

Reversal film. Film that can be processed to give a positive image, such as a color slide film. Some black and white films can be reversal processed.

Color reversal film after development is called a transparency and can be viewed directly using a loupe or projector. Reversal film mounted with plastic or cardboard for projection is often called a slide.

Colour Reversal Film
Colour reversal or slide film is available at similar speeds to Black & White negative film. but only has a latitude of about 1/2 stop.

Color Reversal Film Processing.-
The processing of Kodachrome films (the K- 14 process) is relatively complicated and can be carried out only in licensed laboratories with special equipment.

These are color reversal films. Again, in general, the lower the ISO the finer the grain, and the lower the contrast. Recently, new film emulsions in the ISO 50 to ISO 100 range have been released.

Transparency or Reversal Film
Over Exposure. Loss of highlight detail. Bright areas will 'burn out' leaving just a clear section of film . When it's gone it's gone.

Velvia, however, is a very high contrast and high color saturation film, rather unlike most other reversal films. And these facts get lost in that single ISO 50 rating.

Reversal film, on the other hand, is another story. Exposure latitude of perhaps one stop under and one-half stop over is often cited. But I have always maintained that it is pointless to think in terms of latitude when using this type of film.

In the camera, too much light causes overexposure-this makes negative film look too dark and reversal film look too light. Underexposure (too little light) has the reverse effect.

Fuji 4x5 films : A new generation of daylight-type color reversal film offering the finest grain of any color reversal emulsion now available. Ideal for a wide range of professional applications, from product photography and landscapes to portraits ..

Sure, offer as well as demand for reversal film is shrinking. But keeping shooting E6 as much as we can is the best way to ensure continuity of supplies. Let's keep on doing it!
Happy shooting,

SLIDE FILM - Film used in making slides. Also known as "Transparency film," "Positive film" or "Reversal film."
SLOW FILM - Film with relatively low sensitivity to light - typically having a film speed in or lower than the ISO 50 range.
