A deliberate gap, recess, or shadow line built into the junction between two surfaces, panels, or materials within an exhibit or installation to create visual separation, add depth, and elevate the perceived quality of the construction. Reveals are a hallmark of refined fabrication and architectural detailing and are used to transition between different materials, define edges, and prevent the flat, undifferentiated appearance that results when surfaces meet without intentional detail. The width and depth of a reveal are specified during the design phase and must be executed precisely in fabrication to achieve the intended visual effect.
