How are photographic images made permanent?

Photographic images are made permanent through various processes, depending on the medium used. In traditional film Photography, light-sensitive chemicals on the film capture images, which are then developed and fixed to make them stable. In digital photography, images are stored as digital files on memory cards or drives, where they can be saved indefinitely. Additionally, prints can be made using ink or photographic paper, which can also be treated to enhance longevity.
