Headshot studio

Input: one casual phone selfie. Output: a set of professional-grade headshots at platform-correct ratios — LinkedIn polished, ID / passport, editorial / creator portrait, casual founder shot — with the same face across every variant. The bar is "plausibly a real photoshoot" not "obvious AI filter".

When to Use

• Solo creator, founder, or job-seeker needs a LinkedIn / speaker bio / About page headshot and doesn't want a photographer
• User has one usable selfie (well-lit enough, face clearly visible) and wants 3-5 polished variants
• They say "headshot", "LinkedIn photo", "professional profile pic", "polish this selfie", "make this a pro photo", "editorial portrait"
• They need the same face across multiple styles (not just one image)

Don't use for: group photos, full-body fashion shoots (different model family), or character consistency across video clips (use gen-ai-use with a generated reference).

Prerequisites

Ask before running (combine into one message):

1. Source selfie — path or URL. Must be frontal, eyes visible, decent lighting. If the source is blurry or dark, recommend re-shooting before generation.
2. Styles wanted — which variants? Default set is LinkedIn / editorial / casual / ID. Offer mix-and-match.
3. Wardrobe direction — should the model wear the same outfit as the source, a suggested one ("dark blazer", "neutral knit"), or let the model pick per style?
4. Aesthetic lean — warm / cool, editorial-magazine / corporate-safe / creative-tech?
5. Background — neutral studio, office, outdoor, plain color, blurred environment?
6. Aspect ratios needed — 1:1 for LinkedIn/ID, 4:5 for editorial, 9:16 for reels / stories?

How to Run

1. INTERVIEW        → confirm source, styles, wardrobe, ratios
2. ENHANCE SOURCE   → upscale the selfie for better identity lock
3. GENERATE         → i2i per style, face reference locked
4. REVIEW           → verify face consistency; check hands, eyes, ears
5. REGENERATE       → one-at-a-time for misses
6. DELIVER          → per-platform folder with correct ratios

1. Upscale the selfie first. Gemini / Flux i2i models lock identity better from a sharp reference:

   gen-ai enhance -i selfie.jpg -m topaz-upscale-image --download ./headshots/src

   Alternatively use picsart-enhance for a lighter pass.

2. Estimate the batch.

   gen-ai batch run headshots.json --dry-run

3. Generate per style with the enhanced selfie as reference. Face identity locking is the whole game — always pass -i:

   gen-ai generate -m gemini-3-pro-image -i ./headshots/src/selfie-hd.png \
     -p "professional LinkedIn headshot of the same person, dark blazer over neutral knit, soft studio lighting, clean charcoal background, shallow depth of field, 50mm lens look, editorial corporate photography" \
     --ar 1:1 --download ./headshots/linkedin

4. Review each output for identity drift. Common failure modes:

   • Face looks subtly different (different nose, jawline, eye shape)
   • Skin oversmoothed into uncanny-valley territory
   • Hair changed color or style beyond the prompt
   • Eyes slightly misaligned

   If the face drifted, regenerate with a stronger prompt: "exact same face as the reference image, matching bone structure, skin tone, eye color, and hair exactly".

5. Deliver in a platform-correct folder layout.

   ./headshots/
     linkedin/  1:1, 1200×1200
     ig/        4:5, 1080×1350
     story/     9:16, 1080×1920
     id/        1:1, 600×600, neutral background
     editorial/ 4:5, wider crop

Quick Reference

Avoid flux-2-pro here — it's t2i-dominant and will drift the face more than Gemini or Kontext.

Procedure

• Source quality is everything. A blurry, backlit, or heavily-filtered selfie produces drifted faces. Spend 30 seconds asking the user to re-shoot in daylight before burning credits.
• Always upscale the source first. Sharper reference = tighter identity lock downstream.
• Use the phrase "the same person" or "exact same face as reference" in every prompt. Models respond to explicit identity cues.
• Generate 1-2 variants per style first, verify identity, then scale up. Don't batch 12 before checking the first one.
• Keep wardrobe + lighting changes explicit per style — don't leave them ambiguous. "Dark blazer, neutral knit" beats "business clothes".
• Check eyes, ears, and hairline — these are where AI headshot drift hides. Ears especially: asymmetric, missing, or fused ears are a giveaway.
• Avoid extreme angles or expressions in the prompt — profile shots, wide laughs, tilted-head glamour poses all break identity. Frontal, neutral-to-slight-smile is the safe zone.
• Upscale finals to 2048+ for LinkedIn / About-page use. The source was phone quality; the output should not ship at that resolution.

Pitfalls

• Face drifts subtly across variants — source too low-res, prompt didn't say "same person", or model wasn't an identity-locking i2i. Fix: upscale source, use Gemini 3 Pro, explicit identity phrasing.
• Uncanny plastic skin — over-processed look. Add "natural skin texture, subtle pores, no beauty retouching" to the prompt.
• Asymmetric or fused ears — regenerate; don't try to patch in post. Gemini 3 handles this better than older models.
• Wrong aspect ratio for LinkedIn — LinkedIn profile is effectively circular cropped from 1:1. Plan compositions with centered face + breathing room on all sides.
• Batch-generating before verifying one — if style 1 drifted, styles 2-4 will too. Always verify the first output before fanning out.
• Forgetting to upscale the final — shipping a 1024×1024 headshot to LinkedIn looks soft on retina screens. Always final-upscale.

Verification

Run gen-ai whoami to confirm authentication, then re-run the failed command with --debug.
