Filmnegatívok
Filmnegatívok, often referred to as film negatives, are the intermediate photographic image produced during the development of photographic film. They are the inverse of the final positive image, meaning areas that were light on the original scene appear dark on the negative, and vice versa. This inversion is a fundamental part of the photographic process. The negative is then used to create a positive print, typically by exposing photographic paper to light passed through the negative, or in digital photography, by scanning the negative. The color of the negative depends on the type of film used. Black and white negatives have varying shades of gray, while color negatives have a distinctive orange or brown mask, which is a byproduct of the color development process and helps to achieve accurate color reproduction in the final print. The emulsion on the film contains silver halide crystals that are sensitive to light. When exposed, these crystals undergo a chemical change. During development, these exposed crystals are converted into metallic silver, forming the visible image. The unexposed crystals are then removed. Negatives are sensitive to light and must be handled and stored in dark conditions to prevent unwanted exposure or degradation. They are a crucial archival medium for preserving photographic images.
