Headshots are photographs that put a clear focus on a subjects face and give the viewer

Headshot originated in 1839 with Robert Cornelius when he started taking selfies.

In 1854, André-Adolphe-Eugène Disdéri came up with a more affordable process of photographic portraiture by cutting up full-sized plates into 4 separate small portraits. The photos would later be known as Carte-de-visite, or visiting cards and are thought to be the first business cards.

In modern times, headshots are usually used for methods of identification and professions like acting or music for marketing purposes.

Most of the time headshots implement a lot of negative space like a white background to remove all other focus other than the subject.
