Symmetric Neck Joint (also known as ghost mannequin or invisible mannequin editing) is a precise retouching technique used to create a natural, 3D appearance of clothing without showing the mannequin or model. This process involves combining multiple images—typically the front, back, and inner neck areas—to produce a clean, symmetrical look that highlights the garment’s true shape and fit. By maintaining perfect alignment, balanced lighting, and realistic fabric texture, the symmetric neck joint technique ensures that each product image looks professional, consistent, and ready for e-commerce presentation.
