Photography can be used for many applications such as advertising, fashion, photojournalism, and portraiture. Advertising photography aims to sell products by featuring them in attractive images. Fashion photography promotes clothing brands by showing their items on models. Photojournalism documents real-life events and issues through images to tell stories. Portraiture captures facial expressions and details to characterize individuals. Across applications, photography may involve controlled studio shoots or candid outdoor photos, with variations in lighting, lenses, and minor post-production editing.
