LinkedIn Professional Photo — Side-by-Side Results
Prompt
"A candid, selfie-style LinkedIn-ready photo of a 28–35-year-old professional influencer with shoulder-length dark hair (neatly styled), light natural makeup, wearing a smart casual blazer over a plain tee and clean jeans, holding a phone at arm’s length and looking near the camera with an approachable, confident smile. Shot in a real café during a work break with a laptop and coffee on the table, subtle background blur, natural window light, realistic phone-camera perspective and slightly imperfect framing like an Instagram story. Keep it authentic and everyday (not editorial), well-groomed and business-appropriate with soft, professional natural lighting."

Flux 2 Strengths
- Best for iterative headshot refinement: strong image-to-image editing for adjusting pose, crop, background, and wardrobe while keeping a consistent “corporate” look
- LoRA support enables consistent personal branding (e.g., repeatable lighting, backdrop, and wardrobe style across a team or campaign)
- Face-swap support can help align identity across multiple variations (useful for selecting the best expression/angle while keeping the same person)
- Up to 4MP output supports crisp LinkedIn-ready crops (head-and-shoulders) without looking soft or overly compressed
- Flexible style transfer makes it easier to steer toward conservative, business-appropriate aesthetics (neutral tones, subtle contrast, natural retouching)
Flux Ultra 1.1 Strengths
- Excels at photorealistic detail: convincing skin texture, hair detail, and natural lighting that reads like a real studio portrait
- Strong “out-of-the-box” LinkedIn look: clean, premium headshots with minimal prompt complexity
- High fidelity in fabrics and accessories (blazers, shirts, ties, glasses) that helps the portrait feel credible in a corporate setting
- Great for final selects: premium-quality output that often needs fewer reruns to get a polished, professional result
- Better choice when realism is the top priority and you don’t need extensive editing workflows
Verdict
If your priority is the most photorealistic, premium-looking LinkedIn headshot with minimal tweaking, Flux Ultra 1.1 is typically the better pick—and it’s also straightforward on cost at 16 credits per image.
If you need a production workflow—editing an existing photo, iterating on background/wardrobe, maintaining brand consistency via LoRA, or generating multiple variations while keeping identity stable—Flux 2 is the more versatile option. Note that Flux 2 pricing varies: 22 credits (Standard) or 16 credits (Klein 9B) per image.
