Studio-quality portrait cut-outs with preserved colour profiles
True alpha, ICC-safe exports, and soft hair edges — for photographers who deliver to clients.
The problem
Portrait compositing requires correct straight alpha, preserved colour profiles, and soft edges on hair. Most background removal tools either destroy the ICC profile, export premultiplied alpha, or binarize hair edges into hard, unnatural cutouts that are immediately obvious to any art director.
The NSS solution
NSS exports verified straight-alpha PNGs with ICC profile preservation. Every export is checked for correct soft alpha on semi-transparent edges. Free, unlimited, and compatible with every professional tool.
How to use it
- 1
Headshot sessions for corporate clients
Batch-process full headshot sessions, export consistent transparent PNGs, and hand off to the client's design team for placement on branded backgrounds.
- 2
Portrait compositing for creative projects
Cut subjects from studio backgrounds for fantasy, editorial, or environmental composites — with soft, natural hair edges.
- 3
School and event portrait packages
Process large batches of portraits for school packages, sports teams, and events. Export as ZIP for straightforward delivery.
- 4
Background replacement for portrait studios
Replace the physical backdrop with a custom digital background post-shoot — cleaner than in-camera green screen.
Step-by-step guide
- 1
Shoot with a contrasting backdrop
Any solid colour works. Classic grey, white, or a mid-tone that contrasts with the subject's hair gives the cleanest AI results.
- 2
Upload at full resolution
NSS processes up to 4096 × 4096 px. For portrait sessions, upload your deliverable resolution, not a web proxy.
- 3
Use Best Quality mode
RMBG-2.0 produces noticeably better hair edges than the fast model. Worth the extra model download time for client work.
- 4
Fine-tune edges
Use Feather (2–4 px) for a natural soft edge. Use Decontaminate if the backdrop was a coloured backdrop that's bleeding into hair.
- 5
Verify and export
The alpha integrity check runs automatically. Green checkmark = safe to deliver to client.
Common questions
Do ICC profiles survive the export?
Yes. NSS reads the ICC profile from raw bytes and embeds it in the PNG at export. No colour conversion is applied.
Does it handle complex curly or textured hair?
Best Quality (RMBG-2.0) mode handles complex hair significantly better than the fast model. Very fine flyaways against a matching background remain challenging — use the restore brush at low opacity for those.
Is the export compatible with Photoshop's compositing?
Yes. NSS exports straight-alpha PNG which composites correctly in Photoshop, Lightroom, Affinity, and all professional tools.
Can I use this for green screen shots?
NSS is a general AI-based background removal tool, not a chroma-key tool. It works on green screen subjects but conventional chroma-key (Resolve, Premiere, After Effects) will give more precise results for green screen work.
