Slide Film Types (Color Reversal Film)

Slide Film ProcessingSlide film [E-6], also known as reversal film, is a type of film that creates a positive image instead of negative images or negatives [C-41].
More on the differences between E-6 and C-41

Slide film example

Slide film produces vibrant and rich colors that come closer to the actual colors and tones present during exposure. When processing film, you can choose to have the transparency mounted in a cardboard or plastic holder (The Darkroom uses plastic holders) for projecting is a slide projector.

These transparencies or diapositives (abbreviated as “diafilm”) come in sizes from 35mm, medium format film, and large format, such as 8×10 sheet film. Modern-day color reversal film is processed with E-6 processing. The major film brands for color reversal film are Kodak and Fuji. The ISO film speed of slide film is a typically slow film that results in extremely fine grains to produce sharper images.

Velvia 100

Velvia 100 is a daylight-balanced color transparency film that exhibits incredibly high color saturation reproduction along with a super-fine grain structure to render imagery cleanly and clearly. It has a medium-speed nominal sensitivity of ISO 100/21° when processed in E-6 or CR-56 processes and can effectively be pulled one-half stop or pushed one-stop with Minimal variations in color balance and gradation.

The introduction of new-generation cyan, magenta, and yellow couplers gives this film its uniquely saturated look and also offers anti-fading characteristics for ensured color image storage permanence. High overall contrast and vivid color reproduction make this film ideal for use in a wide range of photographic applications and are especially well-suited for use in scenic and nature photography.
