Uniquely interesting and definitely modern! Vertical Spectrum is produced with high definition photography with artistic digital enhancement. The process for framing and mounting is called Archival Gold. This includes mounting the photo to an 1/8" clear acrylic panel while using Sintra as the backing board. A stainless steel frame is mounted to the back of the Sintra so the piece can be hung on the wall. Archival Gold is a cutting edge process which provides extra protection from moisture and dust particles that can damage your limited edition piece of art.
