Voyeurism may be tolerated or even appreciated if the people viewed are exhibitionists. This relationship is typically role-play where the exhibitionist pretends to not know of the voyeur's presence.
A subset of voyeurs derive sexual pleasure from looking under articles of clothing, an act known as an upskirt. This can be accomplished by camera or simply by a chance viewing up skirts or trousers. Some voyeurs also derive pleasure by looking down shirts and viewing breasts, particularly when a person is bending over. This is commonly referred to as a downblouse.
