LinkedIn Professional Photo — Side-by-Side Results
Prompt
"A candid phone-camera portrait of a 28–35-year-old professional influencer with shoulder-length dark hair, minimal makeup, wearing a navy blazer over a simple white tee and tailored trousers, holding their phone slightly below eye level and looking near the lens with an approachable confident smile. Shot in a real coworking space lounge with a neutral wall and a laptop + coffee on the table in the background, natural window light from the side, subtle shallow depth of field like an Instagram Story “heading into meetings” check-in. Keep it authentic and unretouched (light skin texture visible), business-appropriate, clean and well-groomed, casual UGC vibe rather than editorial."
