Jan Vermeer in the context of "Pigments"

Leadlights, leaded lights or leaded windows are decorative windows made of small sections of glass supported in lead cames. The technique of creating windows using glass and lead came to be known as came glasswork. The term 'leadlight' could be used to describe any window in which the glass is supported by lead, but traditionally, a distinction is made between stained glass windows and leadlights; the former is associated with the ornate coloured-glass windows of churches and similar buildings, while the latter is associated with the windows of vernacular architecture and defined by its simplicity.

Since the traditional technique of setting glass into lead cames is the same in both cases, the division between 'leadlights' and 'stained glass' became less distinct during the late 20th century. The terms are now often incorrectly used interchangeably for any window employing this technique, while the term 'stained glass' is often applied to any windows, sculptures or works of art using coloured glass.

The term composition means "putting together". It can be thought of as the organization of art. Composition can apply to any work of art, from music through writing and into photography, that is arranged using conscious thought. In the visual arts, composition is often used interchangeably with various terms such as design, form, visual ordering, or formal structure, depending on the context. In graphic design for press and desktop publishing, composition is commonly referred to as page layout.

The composition of a picture is different from its subject (what is depicted), whether a moment from a story, a person or a place. Many subjects, for example Saint George and the Dragon, are often portrayed in art, but using a great range of compositions even though the two figures are typically the only ones shown.

Genre painting (or petit genre) is the painting of genre art, which depicts aspects of everyday life by portraying ordinary people engaged in common activities. One common definition of a genre scene is that it shows figures to whom no identity can be attached either individually or collectively, thus distinguishing it from history paintings (also called grand genre) and portraits. A work would often be considered as a genre work even if it could be shown that the artist had used a known person—a member of his family, say—as a model. In this case it would depend on whether the work was likely to have been intended by the artist to be perceived as a portrait—sometimes a subjective question. The depictions can be realistic, imagined, or romanticized by the artist. Because of their familiar and frequently sentimental subject matter, genre paintings have often proven popular with the bourgeoisie, or middle class.

Genre subjects appear in many traditions of art. Painted decorations in ancient Egyptian tombs often depict banquets, recreation, and agrarian scenes, and Peiraikos is mentioned by Pliny the Elder as a Hellenistic panel painter of "low" subjects, such as survive in mosaic versions and provincial wall-paintings at Pompeii: "barbers' shops, cobblers' stalls, asses, eatables and similar subjects". Medieval illuminated manuscripts often illustrated scenes of everyday peasant life, especially in the Labours of the Months in the calendar section of books of hours, most famously the Très Riches Heures du Duc de Berry.

Procuring, pimping, or pandering is the facilitation or provision of a prostitute or other sex worker in the arrangement of a sex act with a customer. A procurer, often called a pimp if male, or a madam if female, (though the term "pimp" is often used for female procurers as well) or a brothel keeper, is an agent for prostitutes who collects part of their earnings. The procurer may receive this money in return for advertising services, physical protection, or for providing and possibly monopolizing a location where the prostitute may solicit clients. Like prostitution, the legality of certain actions of a madam or a pimp vary from one region to the next.
