Colour Reversal Film | Reversal, Slide or Transparency Film Scanning

In photography, reversal film or slide film is a type of photographic film that produces a positive image on a transparent base. Instead of negatives and prints, reversal film is processed to produce transparencies or diapositives (abbreviated as "diafilm" or "dia" in some languages) Reversal film is produced in various sizes, from 35 mm to roll film to 8×10 inch sheet film.

There are different types of films today:

  1. Print films are standard, commonly used films. They produce transparent negatives (images with inverted colors) that are printed on photographic paper with use of an enlarger or by contact printing. These films can be color or black-and-white.
  2. Color reversal film (or "slide film".) works the same as print film but it doesn’t invert colors. It makes diapositives (transparencies) which can be placed in small metal, plastic or cardboard frames and used as slides in projectors or slide-viewers. There are also color reversal sheet films of large format. They are used by professional photographers in order to produce very-high-resolution images which can be later scanned digitally.
  3. Black-and-white reversal film exists but is used rarely. Positive black-and white slides can be produced from negative without much problems and this method is more commonly used.
  4. Instant films are exposed and developed by instant camera after a photograph has been taken, without need to be developed in laboratory.

Some films are made to be sensitive to non-visible radiations: ultraviolet and infrared.

Those films made to be sensitive to X-ray radiation are used for medical imaging and can for instance see broken bones or foreign objects in body without need for invasive surgery.

Photographs used different types of films according to their characteristics. “Film speed” describes a film's sensitivity to light. “Slow” films have lower sensitivity and have to be exposed to light much longer to achieve same image as some “faster” films.

Scanning resolutions are guided by the film type you bring in. From short orders to bulk orders we can confidently support your slide scanning requirements.

All slides are professionally cleaned and digitised to the correct dpi,
which we will access, before entering our post production suite where all images are toned
and sharpened before being output to your desired format TIFF or JPEG digital files.
