Problem
Cutout objects have no edge color integration, making them look pasted onto the background.
Solution
Root Cause / Diagnostic:
Hard-edged cutouts lack the natural optical phenomenon of light wrap, where background photons bleed around subject borders. Without edge color integration, subjects look like paper cutouts pasted onto a flat backing card.
Actionable Fix:
1. Create a light wrap effect: clip an inverted mask of the subject, expand by 3–5 px, blur by 4 px, and fill with the average color of the underlying background set to Screen (opacity 20%–35%).
2. Apply Photoshop's "Decontaminate Colors" feature (or paint matching rim color on an inner-clipped layer) to eliminate leftover green/white studio matte fringe.
3. Inspect the subject perimeter at 100% zoom against both dark and bright backgrounds to confirm seamless, natural photon bleeding.
Pro Tip:
Add a subtle 3-pixel light wrap on all cutout edges: bleeding 20% background luminance around the subject simulates natural camera optical dispersion.
