In the modern era, various manufactured boards have been employed such as hardboard (often known by the brand name Masonite), MDF and plywood. Metal supports, usually copper, have also been employed for panel painting.
parafoveal vision - Sight outside the zone of sharp focus in the eye (foveal vision).
passage - A certain part or area in a work of art.
pastel - Pigment bound together using gum to make a drawing stick; also the art produced using this medium. In color terminology, pastel refers to tints of color or pale colors.

pencil - A thin rod (the lead) of graphite, coloured wax or charcoal encased in wood used as a drawing or writing implement. Mechanical pencils, grip the lead in a pen-like holder. The graphite in pencils is a mixture of graphite and clay: the more clay the harder the pencil and the lighter the mark it makes (a 6H for example); the less clay the softer the lead and the blacker the mark (an 8B for example).

picture plane - The flat plane occupied by the surface of a painting, often referred to in discussions of perspective.
piece mold - A mold made in several pieces to allow easy removal of a casting and minimise damage to the mould itself.
pigment - The powdered colored matter within paint and pastels. Pigments can be organic or inorganic, manmade and natural. Some inert powders are also classed as pigments unless used in excess. See also filler, lightfastness and fugitive.

The dots of color blend in the viewer's eye to create the illusion of colour and light when viewed at an appropriate distance. The most famous exponent was George Seurat. See also optical mixing and stippling
polarising filter - In photography, a filter that blocks out polarised light from a given angle. Can be used to reduce or eliminate reflections when photographing paintings.
polychrome - Having many colors; usually used when describing sculpture that has been colored in some way.
polymer clay - A clay-like synthetic sculpting material made from polymer particles bound together that set into a solid when heated at low temperatures. Brand names include Sculpey and FIMO.
polyptych - A painting made up of more than three panels. See also triptych and diptych.
Pop Art - An art movement popular in the 1960s that used familiar products and images from popular culture and used them in iconic ways. Two of the best-know exponents were Andy Warhol and Roy Lichtenstein.

resist - A substance applied to a surface to prevent ink or paint from taking to it.
resolution - The number and size of pixels that form a digital image or print. Resolution is expressed commonly in pixels per inch, ppi, and is independent of its physical dimensions, so a 2"x5" image can be both high resolution (300ppi) and low resolution (72ppi). When referring to the resolution of a printout or printer (such as common inkjets) resolution is expressed in dots per inch, dpi.
