Humanize AI Portrait Photo

I have a single PNG portrait that was generated with AI. Before I upload it as my social-media profile picture, I need it to look and register exactly like a naturally shot photograph—both to the human eye and to common online “AI image” detection tools.

What I expect: subtle retouching that introduces authentic photographic cues (lighting micro-variations, organic skin texture, natural lens artefacts, believable metadata, etc.) without compromising image quality. The end result should feel convincingly human while retaining the original likeness and resolution.

Deliverables
• Finalised PNG at original resolution, plus an optional platform-optimised copy
• A short note outlining the key adjustments you made and any tools or plug-ins employed (Photoshop, Lightroom, Topaz, GIMP, etc.)

Acceptance criteria
• The edited file must pass at least two publicly accessible AI-generation detectors (send me the links or screenshots of the checks).
• No visible degradation or unnatural artefacts when viewed on standard mobile and desktop screens.

If you have a proven method for de-AI-fying portraits, I’d love to see it in action.
