Creating a convincing 3D ghost mannequin effect requires two or more shots of each garment and careful masking in Photoshop.
Front-on, on mannequin. Also shoot the inside of the collar with the mannequin removed.
Use the Pen Tool or Subject Selection. Always refine edges around fine fabric details.
Stack the layers, align with Warp, and blend with a graduated mask. If this workflow sounds complex, our ghost mannequin editing service handles everything.
