A Model is a person with a role either to promote, display or advertise commercial products (notably fashion clothing in fashion shows), or to serve as a visual aid for people who are creating works of art or to pose for photography. Though models are predominantly female, there are also male models, especially to model clothing. Models may work professionally or casually.
A promotional model is a model hired to drive consumer demand for a product, service, brand, or concept by directly interacting with potential consumers. The vast majority of promotional models tend to be attractive in physical appearance. They serve to provide information about the product or service and make it appealing to consumers.
A professional photographer may be an employee, for example of a newspaper, or may contract to cover a particular planned event such as a wedding or graduation, or to illustrate an advertisement. Others, like fine art photographers, are freelancers, first making an image and then licensing or making printed copies of it for sale or display. Some workers, such as crime scene photographers, estate agents, journalists and scientists, make photographs as part of other work.

Renting, also known as hiring or letting, is an agreement where a payment is made for the temporary use of a good, service or property owned by another. A gross lease is when the tenant pays a flat rental amount and the landlord pays for all property charges regularly incurred by the ownership. An example of renting is equipment rental. Renting can be an example of the sharing economy.

When renting real estate, the person(s) or party who lives in or occupies the real estate is often called a tenant, paying rent to the owner of the property, often called a landlord (or landlady). The real estate rented may be all or part of almost any real estate, such as an apartment, house, building, business office(s) or suite, land, farm, or merely an inside or outside space to park a vehicle, or store things all under Real estate law

A camera is an optical instrument used to record images. At their most basic, cameras are sealed boxes (the camera body) with a small hole (the aperture) that allow light in to capture an image on a light-sensitive surface (usually photographic film or a digital sensor). Cameras have various mechanisms to control how the light falls onto the light-sensitive surface. Lenses focus the light entering the camera, the size of the aperture can be widened or narrowed to let more or less light into the camera, and a shutter mechanism determines the amount of time the photo-sensitive surface is exposed to the light.
