What is a metallic photo finish and how does it differ from other types of finishes used in photography?

A metallic photo finish is a type of print that has a shiny, metallic appearance, giving the image a vibrant and reflective quality. This finish is achieved by printing the image on a special paper with a metallic coating. It differs from other types of finishes, such as matte or glossy, by its unique reflective properties that make colors appear more vibrant and details more pronounced.
