Comment créer un wallpaper pour mobile avec Midjourney ?

Le brief : imaginer une illustration avec un personnage qui ressemble à Jimmy Hendrix fumant une cigarette dans un décor coloré.

Objectif final : réaliser avec l’image un fond d’écran (wallpaper) pour un mobile.

Premier essai, on écrit directement un prompt dans Mijourney v 6.0 (Commande /imagine).

jimmy hendrix smoking a cigarette tye die color scheme --ar 9:20 --v 6.0 --style raw

Pour cet exemple, nous allons prendre l’image 4 (celle en bas à droite). Le format 9:20 est idéal pour transformer l’illustration en wallpaper pour mobile.

Peut-on obtenir mieux ? Probablement, nous allons demander à ChatGPT s’il en est capable en s’appuyant sur DALL-E et un des GPTs dénommé Prompt Perfecter.

Generate a Dall-E3 prompt for a illustration where jimmy hendrix is smoking a cigarette tye die color scheme format 9:20

Le résultat obtenu via DALL-E/Prompt Perfecter est plutôt coloré et précis. Toutefois notre objectif n’était pas tant d’avoir une belle image mais d’obtenir un prompt optimisé.

{« prompt »: « Illustrate a character inspired by Jimmy Hendrix in a 9:20 portrait format. The character should be captured smoking a cigarette. Emphasize a tie-dye color scheme with vibrant swirls of red, blue, green, and yellow. The background should be psychedelic and abstract, complementing the tie-dye theme. Ensure the lighting is warm and slightly surreal, accentuating the character’s facial features and the smoke from the cigarette. »}

Ce Prompt Perfecter est parfait pour DALL-E mais le résultat s’avère décevant avec Midjourney. Nous allons donc soumettre le brief initial à un autre des GPTs dénommé Midjourney Prompt Generator Pro.
