Effect
Shape Mask
Mask the image with geometric shapes and soft edges.
Shape masks crop or fade an image into geometric apertures: circles, rectangles, soft vignettes with hard intent. Lenses and optical printers had physical mattes; digital masks made the same language editable.
Edge softness decides between stamp-cut and dreamy portal.
