This document discusses different types of photography and their purposes. Advertising and promotional photography aim to sell products and raise awareness, using controlled shoots and post-production editing. Photojournalism documents real events to accompany news stories, but can also manipulate images to influence viewers. Fashion photography sells clothing through idealized images of thin models, often heavily edited. Portraiture captures subjects' emotions and details through posed or candid shots. Architecture photography styles vary from artistic to realistic depending on the intended use of the image.
