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, right body shape and size is directly related to success. This is particularly true of the female breast, where having their size and shape altered by breast implants is considered crucial for success in the glamour industry. This type of photography is colloquially known as "cheesecake" for women and "beefcake" for men.
