According to Wikipedia:
Glamour photography is a genre of photography in which the subjects are portrayed in erotic poses ranging from fully clothed to nude. The term may be a euphemism for erotic photography. For glamour models, body shape and size is directly related to success.
This type of photography is colloquially known as "cheesecake" for women and "beefcake" for men.
Glamour photography is generally a composed image of a subject in a still position. The subjects of "glamour" photography for professional use are often professional models, and the photographs are normally intended for commercial use, including mass-produced calendars, pinups and men's magazines such as Maxim; but amateur subjects are also sometimes used, and sometimes the photographs are intended for private and personal use only. Photographers use a combination of cosmetics, lighting and airbrushing techniques to produce an appealing image of the subject.
