nonportrait

Nonportrait is a label used in some digital image catalogs and computer vision datasets to denote images whose primary subject is not a portrait of a person. It encompasses landscapes, architecture, still life, wildlife, cityscapes, abstract art, action scenes, and other subjects where a person's likeness is not featured as the focal point. It is not a formal term in art history but a practical tagging convention in data organization.

It is distinguished from portrait by subject matter and composition, often lacking a clearly posed human subject, and by the absence of typical portrait features such as head-and-shoulders framing, gaze engagement, or intentional posing. It may include images with people in the frame if they are not the main subject or are in a non-portrait context.

Used in image-annotation schemas, search filters, and machine learning datasets to separate non-human or non-portrait content from portraits. This helps tasks such as portrait recognition, anonymization, or bias analysis in models trained on mixed imagery. It may appear in metadata fields or annotation schemes.
