Each photograph was made by creating a frequency on a home made spectrograph representing one of the 12 notes in music. The images were archivally printed on kozo paper. Hand made strechers were built to hold the dibond which was primed and covered in gold leaf. The image was laid down over the gold and flooded with resin. Once dry, the piece is wet sanded to remove all reflections then a second pass of resin and polish was hand applied to specific parts of the piece.
