Frames without mats display the image across its full surface, without an intermediate border. The right choice depends mostly on what is being framed and the effect you are looking for. For a standard photo or poster, a wood or aluminum frame with glass is all that is needed: simply match the frame size to the image and choose a finish that works with the décor. For a photo you want to highlight more, a floating frame creates a visible gap between the image and the frame, giving a more polished result without a mat. For framing a three-dimensional object, a medal or a keepsake, a shadowbox provides the necessary depth. Clip frames are the simplest option for posters and prints that get changed regularly, and unfinished frames can be painted or decorated to suit any space.
