Hair matting: prefer soft believable alpha over helmet-hard masks
Route `portrait-hair-matting` supports ID photos, headshots, and posters. Hard masks create helmet hair; over-blurring erases flyaways you might want. Review on the actual backdrop colors—blue, red, or white ID standards. For print, screen-sharpened edges can stair-step on paper; document color space to avoid conversion surprises.
Suggested steps for portrait-hair-matting
- Clarify screen vs print vs official ID color requirements up front.
- Check neck and ear transitions for color fringing after swaps.
- Review at 50% and 100% zoom to avoid plastic smoothing.
remove bg (hair) Q&A
Rainbow fringes in hair—cause?
Background spill; locally clean chroma on the fringe instead of global blur.
Face looks gray after moving to white—why?
Background bounce changed; re-grade skin tones after the swap.
One file for every agency?
If specs differ, split exports—generic masters invite rejection emails.
Printing `portrait-hair-matting`—what breaks versus screen review?
CMYK separation can clip wispy strands; soft-proof with the printer ICC and expect to feather differently than RGB previews.
ID labs mandate a specific blue—skin still shifts after swap?
Calibrate to their swatch, then grade skin separately from the backdrop instead of applying one global color move.
