Reversal film, also known as slide film, is a type of photographic film that produces positive images, or transparencies, rather than negatives. The developed film can be viewed directly with transmitted light or projected onto a screen using a slide projector, making it ideal for presentations, exhibitions, or precise colour evaluation.
Reversal film is valued by photographers for its vivid colours, fine grain, and high contrast. Unlike negative film, which requires printing to view the final image, reversal film allows for immediate visual assessment of composition and exposure, making it a popular choice for professional and creative photography.
