A picture frame is a decorative edging for a picture, such as a painting or photograph, intended to enhance it, make it easier to display, and/or protect it.
Traditionally made of wood, it is still the most common material for making the frame, although other materials are used including silver, bronze, aluminum, and plastics such as polystyrene. A picture frame may be of any color or texture, but it should complement the subject matter, its context and colours.
Elaborate mouldings and gilding are commonly seen especially on older wooden frames. These treatments also complement the décor aesthetic prevalent in the era as well as the painting subject and style. As art and décor both evolved to more contemporary forms, frames too became more simplistic and functional.
Picture frame-making contractors gauge the value and style of the painting or picture to be framed and suggest suitable options. Alternatively the same may be specified by an art consultant and executed by the contractor.
