LinkedIn Professional Photo — Side-by-Side Results
Prompt
"A candid smartphone front-camera portrait of a 28–35-year-old professional with neatly styled shoulder-length hair, light natural makeup, and a tailored navy blazer over a simple knit top, looking slightly off-center toward the lens with an approachable, confident smile. Shot in a real coworking space lounge (neutral wall, soft background blur, laptop and coffee cup on the table), seated casually with one hand adjusting their blazer cuff like they just started recording an Instagram story. Natural window light from the side, realistic skin texture, minimal retouching, LinkedIn-appropriate executive vibe but still everyday and authentic."
