Fényképezgépfilmek

Fényképezgépfilmek, often translated as photographic film or camera film, refers to the medium used in traditional photography to capture images. This film consists of a strip or sheet of transparent plastic film base coated on one side with a gelatin emulsion containing microscopic light-sensitive silver halide crystals. When light strikes these crystals during exposure, a latent image is formed, which is invisible to the naked eye. This latent image is then made visible through a chemical development process.

There are several types of photographic film, primarily categorized by their sensitivity to light (ISO or ASA speed), their color rendition, and their intended use. Black-and-white film captures images in shades of gray, while color film records images in a spectrum of colors. Films also vary in their grain structure, which affects the sharpness and texture of the final image. High-speed films are more sensitive to light, allowing for photography in low-light conditions or with faster shutter speeds, but they typically exhibit more prominent grain. Lower-speed films are less sensitive but produce finer grain and sharper images.

Beyond still photography, photographic film was also the basis for motion pictures, where a sequence of still images captured on film was projected at a rapid rate to create the illusion of movement. While digital photography has largely replaced film in many applications, photographic film remains a vital medium for artistic expression, historical preservation, and specialized photographic techniques. The unique aesthetic qualities and the tangible nature of the film itself continue to appeal to many photographers.
