Votre photo de profil LinkedIn est souvent la première impression que vous donnez à un recruteur, un client ou un partenaire commercial. Une étude de LinkedIn montre que les profils avec une photo professionnelle reçoivent 21 fois plus de vues et 9 fois plus de demandes de connexion. Avec les outils IA actuels comme Midjourney, DALL-E 3, Stable Diffusion et FLUX, vous pouvez créer des portraits de qualité studio sans photographe ni studio coûteux. Cette collection de 50 prompts vous donne exactement les mots à copier-coller pour obtenir des résultats professionnels immédiatement.
La qualité d'un portrait IA dépend de trois éléments clés : l'éclairage, l'angle de prise de vue et l'arrière-plan. Pour LinkedIn, l'éclairage doux en studio, un angle légèrement au-dessus du niveau des yeux et un fond neutre (gris clair, blanc ou brun professionnel) fonctionnent le mieux. Évitez les arrière-plans trop complexes qui distraient du sujet. Voici vos 50 prompts organisés par style et usage.
