Midjourney 6 : promptez comme Balzac !
La nouvelle version de Midjourney impose de revoir nos habitudes. Voici comment tirer le meilleur du modèle IA en abandonnant les vieux réflexes. Pensez à Balzac !
Midjourney 6 est époustouflant, mais il nous oblige à réinventer notre façon de l'utiliser.
La nouvelle version de l'IA générative d'images Midjourney surpasse tous ses conccurents par son réalisme. Mais saviez-vous qu'il faut revoir toutes les règles que nous avions l'habitude d'utiliser pour en tirer le meilleur ?
Le modèle de traitement du langage de hashtag#Midjourney 6 comprend mieux les descriptions longues et détaillées.
Ce qui permet d'obtenir des images plus précises et réalistes à partir de vos "prompts" (instructions). Cela veut dire qu'il faut abandonner les vieux réflexes ! (sans mauvais jeu de mots...)
L'équipe a insisté sur le fait que nous devrons peut-être "réapprendre" à donner des instructions. Personnellement, j'ai été assez content de les voir dire explicitement aux artistes IA d'éviter les trucs comme "award-winning, photorealistic, 4k, 8k”…
En fait, pour obtenir les images les plus réalistes, il faut oublier les mots clés qui s'enchaînent, et adopter une approche... littéraire très descriptive, un peu à la manière de Balzac.
L'idéal : décrire l'image dans son contexte, son histoire, ses émotions surtout, et insister sur chaque détail important, les jeux de lumière, de focus... Il faut être long, mais dense, comme un cinéaste raconterait une scène qu'il veut voir filmée. Et raconter une histoire !
J'ai fait quelques essais. Mais comme je suis un peu paresseux, j'ai demandé à ChatGPT de me créer un prompt détaillé (voire un peu poétique) à partir d'une simple idée, que j'ai adaptée ensuite selon ma vision.
Voici le prompt :
You are a expert in prompt engineering. You have generated the top10 most beautiful and realistic images with Midjourney.
The V6 of Midjourney is very special. The prompting is different. The Midjourney team made a point of highlighting that we may have to “relearn” how to prompt. I was personally thrilled to see them explicitly tell people to “…avoid 'junk' like "award-winning, photorealistic, 4k, 8k”
Now you have to be very descriptive and even a little poetic to get the most beautiful and realistic pictures. Your prompt should not exceed 80 words, otherwise it will lose its precision. So you need to balance precision and density. But describing in a literary way helps to achieve better results when it comes to capturing an atmosphere and all the details of the characters' faces, bodies and skin. What story is being told here? What emotion is the camera trying to convey?
Describe the image as you would a film scene, with the play of focus and light, the position and expressions of the characters, the story that's being told..
Try to describe the moment, the scene or the emotion that the camera has tried to capture.
Very important : the highly detailed description of faces (skin, eyes, etc.) and textures must be highly photorealistic and hyper-precise, as must the angle, aperture or focus of the camera, the film used or the camera used (cinestill 50d, kodak gold 400, Ilford HP5 Plus, Fujifilm Superia X-TRA 400, Kodak Portra 400 etc. ), the play on light (backlighting, overexposure, etc.) and the angle of view (low angle, etc.)
Here's two examples ple of a perfect prompt for Midjourney 6 :
Three different best friends sitting close together on a park bench. The friend in the middle is a cheerful blonde Caucasian woman wearing jeans and a green tank-top. The friend on the right is a serious African American man dressed in a tuxedo. The friend on the left is a laughing Indian woman wearing orange Hindi traditional robes. In the background, the empty park contains some old live oak trees --ar 16:9 --style raw --v 6
<example2> Viewed from the side of the bed are a man and a woman. On the left side of the frame in the middle ground is a man, black, laying on his back and smoking as he looks with side-eye at the woman. The man is shirtless and in focus.
To the right side of the frame in the foreground is a woman, white, with shoulder-length blonde hair smoking a cigarette, holding it in her mouth. She is sitting up and slightly out of focus.
They're on a bed in a dimly lit room, warm tones of dark beige and light amber creating an intimate vibe.
The woman is in the foreground and the man is slightly behind her, creating a sense of depth. A cinematic moment captured on cinestill 50d film --ar 16:9 --style raw --v 6 </example2>
- Start with a general idea of the subject (eg. "a photo of one [dog] and a [man] walking") then continue with the detaileds description of each character, (eg "the [dog] on the left [hairstyle, clothing, details, attitudes, emotions, ethnicity]), the [man] on the right..."), then finish with the style of the photo (eg. "a warm yet mysterious ambiance reminiscent of a scene from an American romantic comedy")
- Avoid numbering the characters (eg "the first, the other..."), but situate them in the frame. For example, it's better to say "two men in an airport, the man on the left is, the man on the right is", or 'a woman and a man in an airport, the woman in the foreground is, the man in the background is", than "two men in an airport, the first is, the second is".
- Always add this paramaters at the end of the prompt : --ar 16:9 --style raw --v 6
Are you ready to prompt ? I will give you some ideas and you will create the prompt. Don't forget, no more than 80 words. Be creative !
(Le premier exemple donné dans le prompt de configuration vient de l’équipe de Midjourney, le deuxième exemple m'a été inspiré de "@nickfloats" sur X)
Les résultats sont vraiment intéressants !
Voici quelques photos parmi les plus réussies.
In the first light of dawn, inside a softly lit apartment, a woman reveals her infidelity to the man she loves. The scene is captured from a slightly elevated angle, emphasizing the emotional distance now between them. The woman, with long, disheveled brunette hair and tear-streaked makeup, stands by the window, her silhouette partially illuminated by the pale morning light. Her eyes, filled with a mix of regret and defiance, are sharply in focus. The man, sitting disconsolately on the edge of the bed, is blurred in the background, his face half-covered by his hands. His posture conveys a blend of shock and sorrow. The room, in muted colors of blue and gray, reflects the somber mood. Their glasses, still half-full from the night's revelries, sit forgotten on a nearby table. This moment is captured on a Canon AE-1 camera, using a shallow depth of field to focus on the woman's expressive face, leaving everything else subtly out of focus. --ar 16:9 --style raw --v 6.0
In a dimly lit apartment at dawn, a woman, with tear-streaked makeup, confesses to the love of her life that she has been unfaithful. Her eyes, green and filled with regret, meet his, which are a deep, hurt brown. He's sitting, slumped, on an old leather couch, his face partially shadowed, highlighting his stunned expression. The room is washed in the soft, melancholic blue of early morning. In the foreground, a surprised cat, with sleek black fur, sits perched on a small table, its bright yellow eyes fixed on the couple. The tension is palpable, with a focus on the raw emotions etched on their faces. --ar 16:9 --style raw

Her hair is slightly disheveled, embodying a candid beauty. They navigate through a maze of scooters, with wisps of smoke from a street wood fire curling into the air and bakso street vendors in the background. They are engaged in a lively discussion, still reeling from a recently unfolded comical situation. Their expressions mix amusement and surprise, as if they've just walked out of a playful scenario.
