Shin worked with the PHA Printshop to create the first PHA Patron Collector Print. It is based on her Tidal Witness sculpture, made from vintage mother-of-pearl buttons. Tidal Reflections zooms in on the sculptural work and captures the subtle-yet-vibrant iridescence of the mother-of-pearl buttons.  In the print, the buttons' ghostly presence glows and changes from different vantage points.
