Female fashion model Junior idol

In Japan, a junior idol (ジュニアアイドル, junia aidoru?), alternatively chidol (チャイドル, chaidoru?) or low teen (ローティーン, rōtīn?), is primarily defined as a child or early teenager pursuing a career as a photographic model (this includes both gravure and AV).

Child actors, and J-pop singers (whose musical genre is often termed idol pop) can also be considered junior idols, and are often featured in photobooks and image DVDs.
Female fashion models (not to be confused with glamour models including gravure idols) also begin their careers typically at age 13 - 15, but are usually not considered junior idols. Child models, whose careers are usually over by their early teenage years, are also not usually considered junior idols.

American Glamour photography

Glamour photography is a genre of photography whereby the subjects, usually female, are portrayed in a romantic or sexually alluring way. The subjects may be fully clothed or seminude, but glamour photography stops short of deliberately arousing the viewer and being pornographic photography.

Glamour photography is generally a composed image of a subject in a still position. The subjects of glamour photography are often professional models, and the photographs are normally intended for commercial use, including mass-produced calendars, pinups and for men's magazines, such as Playboy; 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.
