Beschreibung von Bild V3
すThe next-generation ultra-high-performance AI image generation model 「Imagen 3 (Image v3)」 has dramatically evolved in its 「ability to understand human language (prompts)」 compared to previous models.
Even beginners who "don't know how to give instructions to AI" or "can't get the image I envisioned" can easily produce high-quality images that look like they were drawn by a professional photographer or illustrator, once they grasp the basic tricks.
This article thoroughly explains techniques to bring out 100% of Image v3's performance, from basics to applications, divided into chapters.
Chapter 1: Imagen 3's "Three Overwhelming Features"
Before learning techniques, let's first understand how Image v3 differs from conventional AI. Understanding these features will completely change how you give instructions.
- Understands everyday conversational language (natural language) as-is
Previous AI required instructions to be given as segmented "words, words, words," but Image v3 accurately understands normal sentences like "a scene where ~ is doing ~." - Remarkably accurate text rendering
It can beautifully draw "specified alphabets and words" without distortion inside images, such as signs, logos, or T-shirt prints. - Outstanding realism of light and texture
It extremely realistically reproduces the physical appearance of the real world, such as skin texture, clothing fibers, water droplets, glass reflections, and twilight light.
Chapter 2: "Magic Prompt Composition Formula" for Drawing Exactly What You Want
A common mistake beginners make is giving instructions with just a single word like "cute cat" or "beautiful scenery." To leverage Image v3's performance, try creating a sentence (prompt) while keeping the following 4 elements in mind.
💡 Formula for Effective Prompts【Subject】 ＋ 【Action/Pose】 ＋ 【Background/Situation】 ＋ 【Art Style/Lighting】
- Bad Example:
"A woman in a café" - Excellent Example:
"A Japanese woman in her 20s (subject) is smiling while holding a warm coffee with both hands at a window seat (action). It is raining outside, and water droplets are on the window glass (background). Cinematic lighting, warm atmosphere, high-definition photo taken with a DSLR camera (art style/lighting)"
By connecting these elements specifically into one sentence like this, Image v3 will shape the image in your mind exactly as you imagine.
Chapter 3: Camera Techniques for Pro-Level Photorealistic Images
When you want to generate realistic images with Image v3 that could be mistaken for "real photographs," the trick is to add a few terms used by professional photographers to your prompt.
1. Specify the Angle and Composition- Portrait Photography: Focuses on the face and upper body to bring out the subject's charm.
- Close-up (Macro Photography): Effective for emphasizing details, such as the juiciness of food, water droplets on flowers, or watch gears.
- Low Angle / High Angle: Allows you to specify a powerful composition looking up from below or an objective composition looking down from above.
In AI images, "light" is the most important element.
- Golden Hour Natural Light: Reproduces the soft, golden glow of the evening, creating an emotional atmosphere.
- Studio Light / Softbox: Creates a soft, refined, and beautiful light like model photography.
- Neon Light / Cyberpunk: Can express the vibrant contrast of light and shadow in a night cityscape.
- Beautiful Background Bokeh (Shallow Depth of Field): Makes the subject stand out, instantly giving a professional look.
- Shot with 35mm Lens / 50mm Lens: Produces a natural field of view, perfect for snapshots or portraits.
Chapter 4: Expression Techniques for Mastering Illustration, Anime, and Art Styles
Image v3 excels not only in photography but also in paint texture and animation expression. By simply changing words, you can depict a wide range of art styles.
1. Mastering Anime/Manga Style- Modern Anime Illustration: Creates a vibrant, detailed, and refined anime style.
- 90s Retro Anime Style: Can express slightly nostalgic color tones and a unique texture like cel animation.
- Hand-drawn Chibi Characters: Creates deformed, cute characters perfect for social media icons.
- Watercolor Style (Pale Colors, Bleeding): Creates a soft, transparent, and delicate illustration.
- Oil Painting Style (Thick Impasto, Canvas Texture): Creates a weighty, artistic piece that feels like you can see the paint texture.
- Concept Art: Can express a grand, dramatic world view, like background settings for games or movies.
Chapter 5: How to Use Image v3's Hidden Superpower "Text Rendering"
Master Image v3's greatest strength, "text rendering." You can easily create stylish logos, posters, and signs.
💡 Tips for Adding TextThe most important point is to enclose the text you want written in 「" " (double quotation marks)」 within the prompt.
- Prompt Example:
"A retro neon sign, a night street, blue and pink light. The sign glows with the letters "OPEN"." - Prompt Example:
"A white mug on a marble table. On the surface of the cup, "COFFEE" is beautifully printed."
※Currently, alphanumeric characters (alphabet and numbers) tend to be rendered significantly more clearly.
Chapter 6: "Adjustments and Tips to Avoid Failure" to Step Beyond Beginner Level 1. Don't Give Up After One Try – Roll the "Gacha"
AI image generation produces different images each time, even with the exact same prompt. If "the facial expression isn't what I imagined" or "the placement is slightly off," try pressing the generate button again without changing the words. By trying a few times, you may encounter that one miraculous image.
2. Subtract ElementsIf unnecessary objects appear in the image, try simplifying the prompt or giving an instruction like "don't include ~." Image v3 is smart and will follow instructions like "keep the background simple and white with nothing in it."
3. Use Specific "Material Names"When specifying clothes or accessories, don't just say "clothes." Instead, write specific material or item names like "silk blouse," "denim jacket," or "leather bag." Image v3 will then perfectly differentiate the unique luster and texture of that material.
Summary: Create a World with Words
The best shortcut to mastering Image v3 is to verbalize specific situations, as if you were kindly explaining to someone, "I'd like you to draw a picture like this."
Start by combining just three elements: "subject + location + light." Please experience the thrill of your words transforming into a surprisingly beautiful single image!
