Ghost mannequin photography shows the garment with its shape defined by an invisible form. No model, no face, no styling context — just the garment held in wearable shape by a form the viewer cannot see. The format emerged as an ecommerce standard because it removed model casting from the production process and presented garment construction clearly.
AI on-model photography shows the same garment worn on a photographed or generated human model with full visual context: pose, styling, framing, and lifestyle setting. The customer sees not just the object but the object as it is actually worn. For apparel, this is the format the customer is mentally trying to construct when they look at a PDP.
Most catalogs need both. The conversion weight sits heavily on on-model imagery — that is the hero the customer decides from. Ghost mannequin carries supporting weight on construction detail, colorway variants, and fit shape. A well-built apparel PDP typically has one on-model hero plus two to three ghost mannequins or flat lays.
