In fine art photography and framing, a shadow mount (sometimes called a shadow float mount) is a presentation method where the artwork is raised slightly away from the backing surface, creating a visible shadow around the edges. This separation gives the piece a floating, dimensional appearance and adds depth to the presentation.

Common characteristics:

• Artwork is elevated above the matboard or backing.
• A subtle shadow appears beneath and around the print.
• Creates a museum-style, contemporary look.
• Often used for fine art prints, metal prints, acrylic prints, and mounted photographic artwork.
• Can be combined with a shadow box frame or float frame for additional depth.

Example description:

"This fine art photograph is shadow mounted to create a floating effect, allowing a subtle shadow to form around the artwork and enhancing its depth and visual presence."

If you're referring to photographic paper prints specifically, some framers also use "shadow mount" to describe a print mounted on a rigid substrate (such as foam board, Gatorfoam, or Dibond) and spaced away from the mat or backing to create a three-dimensional effect.
