Lingerie: The model is posed in lingerie, possibly in a fashion sense, but more likely as a glamour shot. Nudity may be required depending on the specific lingerie being used, and how opaque it is.

Glamour: This is a very broad style of modeling which can refer to the black and white Hollywood portrait style of the 1930s-40s, to more risque styles like what can be found in FHM, Maxim, or Playboy style magazines. Implied, partial, or full nudity may be required.

Artistic Nude: This category can encompass nude fashion photography, figure photography and non-figure artistic photography. Figure photography places the emphasis on the model�s nude form, and bold or unusual lighting is often used. In figure photography the model's identity may or may not be revealed. Non-figure artistic nude photography is shot with a theme involving something other than the sexuality of the model. The model is usually identifiable. Implied, partial, or full nudity may be required.

It may often be used to describe Adult Nude work done by established fine art photographers that might otherwise be label pornographic. Implied, partial, or full nudity may be required.

Adult Nude: Still photography of a model or models overtly displaying sexual acts. The sexual acts might be simulated or real. Usually full nudity and beyond are required.
