LinkedIn Professional Photo — Side-by-Side Results
Prompt
"A candid smartphone selfie of a 28–35-year-old professional influencer with neatly styled shoulder-length hair, minimal makeup, and a navy blazer over a simple light top, holding their phone slightly above eye level and smiling warmly while looking near the camera. Shot in a real coworking space with a neutral wall and a desk edge visible (laptop + notebook slightly out of focus), soft natural window light and realistic indoor lighting mix, everyday “about to hop on a call” vibe. Keep it LinkedIn-appropriate and polished-but-real: clean background, approachable expression, natural skin texture, no heavy retouching."

Nano Banana Pro Strengths
- High-end portrait polish for LinkedIn: clean lighting, crisp facial detail, and a marketing-grade finish that reads as “studio headshot”
- Strong prompt understanding for professional constraints (neutral backgrounds, corporate wardrobe, subtle retouching, natural expressions)
- Up to 4K output for sharp profile images and larger crops (banner, speaker bios, press kits) without losing clarity
- Accurate text rendering support is helpful when generating companion assets (e.g., nameplates or simple background signage), though most LinkedIn headshots won’t need text
Seedream 4.5 Strengths
- Excellent for iterative refinement thanks to image-to-image editing—useful for fixing small issues (hairline, collar, tie symmetry, glare, background distractions)
- Versatile looks while staying professional: can shift between modern corporate, creative industry, or executive portrait styles with controlled changes
- Strong value per image at a flat 16 credits, especially for teams running multiple variations and selecting the best take
- High-quality output suitable for LinkedIn profile use, with flexibility to match different brand aesthetics (warm vs cool lighting, office vs seamless backdrop)
Verdict
If your priority is a premium, “finished” LinkedIn headshot with crisp detail and the option to export at up to 4K, Nano Banana Pro is the better pick—especially when you want fewer iterations and a more consistently polished result.
If you expect to edit and refine (swap backgrounds, correct wardrobe details, subtly adjust hair and lighting) and want strong results at a lower per-image cost, Seedream 4.5 is the more flexible, budget-friendly choice for dialing in a believable professional portrait.
