This section header slide introduces the "History of Reversal Film," highlighting its key developments. It invites exploration of the film's evolution from early 20th-century innovations to its modern applications in photography.
Discover the evolution from early 20th-century innovations to modern uses in photography.
The slide outlines key milestones in color slide film's history, starting with Kodak's 1935 introduction of Kodachrome, the pioneering color slide film, followed by Agfacolor's 1936 debut for reversal processing. Post-WWII saw widespread adoption by photographers, though the digital era led to its decline with only niche revivals persisting.
The Reversal Film Timeline begins in 1907 with the invention of Autochrome Plates, the first practical additive color process for glass plate photography, and advances to 1935 when Kodak launched Kodachrome, revolutionizing professional color slide photography. It continues through the 1960s with the affordable Ektachrome film popularizing reversal among amateurs, and into the 2000s, where the rise of digital cameras diminished its dominance but sustained its use in artistic and niche applications.
1907: Autochrome Plates Invented First additive color process enables practical color photography on glass plates. 1935: Kodachrome Film Launched Kodak introduces Kodachrome, transforming color slide photography for professionals. 1960s: Ektachrome for Amateurs Kodak's Ektachrome makes reversal film affordable and popular among hobbyists. 2000s: Digital Shift Impacts Film Digital cameras rise, but reversal film persists for artistic and niche uses.
This section header slide introduces "Processing Methods" as the topic. It features a subtitle that invites exploration of additive and subtractive techniques used to create positive images on transparent bases.
Explore additive and subtractive techniques for creating positive images on transparent bases.
Additive methods in color photography build images by layering filters to combine primary colors, as exemplified by Autochrome plates, producing direct positive transparencies without intermediate negatives for vibrant details. Subtractive methods, in contrast, remove unwanted dyes via chemical cross-processing like E-6 chemistry on reversal films, also yielding direct diapositives with rich, saturated colors and no need for negatives.

| Additive color processes build images by layering filters to combine primary colors, as seen in the pioneering Autochrome plates. This method directly produces positive transparencies, or diapositives, without requiring intermediate negatives for vibrant, detailed results. | Subtractive techniques subtract unwanted dyes through chemical cross-processing, such as applying E-6 chemistry to color reversal films. Like additive methods, it yields direct diapositives—positive images on transparent media—eliminating the need for negatives while achieving rich, saturated colors. |
Reversal film holds a tiny current market share of less than 1% in total film sales, a stark contrast to the 1960s when it dominated with 80% usage among professionals. It also boasts exceptional longevity, offering over 100 years of archival life for storage.

The slide titled "Film Types" serves as a section header introducing various categories of photographic films. It highlights that reversal films range from color to black and white options, tailored to diverse photographic requirements.
From color to black and white, reversal films vary for different photographic needs.
Popular reversal films include color options like the discontinued Kodachrome from 2009 and the revived Ektachrome from 2018. Other types feature black-and-white Fomapan R as a modern choice, instant Polaroid peel-apart films, and large-format sheet films for studio use.
The slide features a quote from renowned photographer Ansel Adams on reversal film, highlighting its unique ability to capture light's magic and transform moments into tangible slides. This quote slide emphasizes the artistic and practical appeal of the medium in photography.
