Transformer une photo en dessin avec ChatGPT exige une méthode précise : le générateur d’images DALL-E ne reproduit pas les pixels à l’identique. Pour obtenir un résultat ressemblant, vous devez lui ordonner de conserver les traits structurels du sujet tout en guidant précisément le médium artistique, la texture des lignes et les ombrages.
Voici 36 prompts testés pour convertir vos images selon des styles graphiques ciblés.
Les techniques de base pour réussir la conversion
Avant d’envoyer votre image dans l’interface, appliquez ces trois recommandations issues du fonctionnement de DALL-E :
- Définir le médium avec exactitude : évitez la formule générique « fais un dessin ». Employez des désignations précises comme
graphite linework,smudged charcoal,2B pencil,heavy ink stipplingouwatercolor wash. - Transférer un style visuel spécifique : téléversez d’abord une illustration de référence et soumettez la consigne suivante :
“Analyze the art style of this image and keep it in your memory, because I want you to apply this exact artistic technique to the next photo I send you.”Envoyez votre photo dans le message suivant. - Corriger les défauts par zone : si la ressemblance faiblit, cliquez sur l’image produite, activez l’outil de sélection (l’icône de pinceau), mettez la zone en surbrillance et rédigez un ajustement précis, tel que
“Make the eyes match the original shape more closely”ou“Tighten the pencil hatching in the shadows”.
Clause d’ancrage pour verrouiller la ressemblance : si ChatGPT modifie excessivement les traits de votre visage, placez cette phrase en tête de votre prompt :
“Analyze the precise facial geometry, eye shape, and structural proportions of the subject in this photo. While applying the following artistic style, do not alter these core proportions so that the subject’s exact identity remains 100% recognizable…”

Portraits académiques au crayon et au fusain
1. Portrait classique au crayon en hachures croisées
Cet angle convient aux portraits artistiques recherchant un niveau de détail élevé et une esthétique de dessin traditionnel sur papier.
“Transform the uploaded photo into a classic cross-hatch pencil portrait. Apply layered, intersecting line strokes that slowly build smooth tonal depth across the face, utilizing controlled single-source lighting from the side. Include fine, delicate hatching worked in around the eyes, set against a plain paper background. Maintain a traditional academic drawing quality, formatted as a 4:5 portrait.”
2. Fusain artistique contrasté
Cette option accentue la profondeur grâce à des zones sombres intenses et des rehauts précis sur les reliefs du visage.
“Turn this photo into a charcoal pencil portrait featuring deep, velvety blacks, soft blended midtones, and crisp, kneaded-eraser highlights on the cheekbones and the bridge of the nose. Keep the face fully recognizable, add a rich textured shadow around the hairline, and leave the background as a smoky gradient with fine-art charcoal quality.”

3. Grille libre de carnet d’esquisses
Ce prompt décompose le modèle sous plusieurs angles et échelles, simulant le travail spontané d’un artiste sur une page blanche.
“Please draw the subject in the uploaded image in a free sketch style. On a bright white background, freely distribute a mix of face close-ups, small scribbles, full-body sketches, and micro-versions so the page conveys their personality. Do not make it look like an organized corporate sheet; instead, make it look like an aesthetic sketchbook page drawn at will by an illustrator where ideas are loosely stacked.”
4. Étude de personnage pour le concept art
Cette mise en page regroupe un portrait principal au trait ferme et des vignettes d’étude des expressions et des détails.
“Reimagine the uploaded photo as a concept-art character study sheet. Keep my exact likeness as the main rough pencil portrait, surrounded by smaller, looser sketches: a profile view, an expression study (one smiling, one surprised), and a hand or detail callout. Use a working-illustrator aesthetic with confident graphite linework, light tonal shading, and an off-white paper canvas in a 3:2 landscape layout.”

16. Gravure sur bois et linogravure
Ce style simule l’encrage artisanal sur papier de mûrier texturé à l’aide de gouges marquées.

L’accent porte sur le geste du pinceau, l’eau et l’usage généreux de l’espace vide sur papier de riz ancien.
“Reimagine the subject of this photo as a traditional Japanese Sumi-e brush painting on aged rice paper. Use fluid, minimalist black ink brushstrokes that capture the spiritual essence and movement of the subject rather than perfect realism. Combine deep black ink for defining lines with dilute, watery grey washes for soft shadows, leaving plenty of empty, negative space.”
21. Crayons de couleur psychédéliques
Ce traitement applique un brunissage appuyé aux crayons Prismacolor avec une palette vive associant teintes néon et vert émeraude.
