 The oils are mixed with an alkyd medium called liquin, which thins the paint and speeds drying time.Edwards and Miller are also separated by distinctions of medium, with pieces under the Miller name more typically executed in acrylic paint on canvas panels as opposed to Edward's more usual use of oils on smooth board.Recently Edwards has also begun working in the digital medium with programs like Painter, enjoying the freedom afforded with computers, although he continues to express a preference for traditional painting techniques.
