Google has officially introduced Imagen 4, the latest version of its text-to-image model, bringing breakthrough improvements in image quality, natural language understanding, and especially the ability to render text in images impressively. This is a powerful tool for content creators, designers, and anyone who wants to quickly and accurately turn ideas into images.
This article will provide an overview of the outstanding features of Imagen 4 and detailed instructions on how to write "prompts" to create the most satisfactory images.
Imagen 4: Superior quality, unlimited creativity
Compared to its predecessors and other imaging AI models, Imagen 4 stands out with the following advantages:
Superior image quality: Imagen 4 produces images that are incredibly detailed, sharp and realistic. Complex details such as fur, fabric textures and natural light are exquisitely reproduced, significantly reducing the artifacts commonly found in previous models.
Deep understanding of language and context: Imagen 4's ability to understand long, complex commands has been greatly improved. The model can capture spatial relationships, quantities, and detailed layout requirements more accurately.
Impressive text rendering: This is one of the most valuable upgrades. Imagen 4 can create images containing clear, easy-to-read text with many different font styles. This opens up great potential for designing posters, invitations, logos and publications containing text. However, according to VietNamNet 's test , Imagen 4's Vietnamese rendering capability is still incomplete.
Google Gemini's Imagen 4 still cannot successfully process Vietnamese text.
Support for various aspect ratios: Users can easily create photos in popular ratios such as 1:1, 16:9, 9:16, 4:3 and 3:4, suitable for many different platforms and purposes.
Minimize errors and distortions: Imagen 4 has been improved to produce more natural and less distorted anatomical images (e.g. hands, faces), a major challenge for previous generations of image-generating AI.
In-depth guide to writing prompts for Imagen 4
To use Imagen 4, you access the Google Gemini app on the app or visit gemini.google.com on the web browser.
Writing effective prompts is key to getting the most out of Imagen 4. A good prompt is like a detailed manual for the AI artist. Here are some tips and structures to help you write “quality” prompts:
1. Structure of an effective prompt
A strong prompt typically includes the following components:
Subject: The main subject of the photo. Describe it as clearly and specifically as possible.
Action: What is the subject doing?
Setting/Environment: Where is the subject? Describe the surrounding space.
Lighting: What the lighting is like in the photo (e.g. soft morning light, bright neon lights, warm sunset light).
Art Style: What style do you want the image to be (e.g. photography, oil painting, animation, digital art, cyberpunk).
Camera Shot & Composition: The camera's perspective (close-up, wide-angle, top-down) and the arrangement of elements in the photo.
Additional Details: Main colors, emotions, textures, and other small details that bring the photo to life.
2. Golden rules when writing prompts
The more specific, the more precise: Instead of writing "a dog," try "a golden-haired corgi happily running across a lush green lawn on a sunny day."
Use strong adjectives: Descriptive adjectives help Imagen 4 "picture" your idea more clearly. For example: "majestic skyscraper", "mysterious forest", "warm smile".
Specify the style: This is the factor that determines the "soul" of the photo.
Photography: "photorealistic", "macro shot", "long exposure", "golden hour photography".
Painting: "oil painting by Van Gogh", "watercolor illustration", "Japanese ukiyo-e style".
Digital: "cyberpunk city", "fantasy art", "3D render", "pixel art".
Experiment with camera angles:
"close-up shot of a cat's eye"
"wide-angle shot of a mountain range"
"drone view of a bustling city intersection"
3. "Formula" for writing prompts for Imagen 4
Here are some "recipes" you can apply:
Basic formula:
[Subject] [what is it doing], [art style]
For example: "A majestic lion with a flowing mane, digital art".
Detailed formula:
[Style], [Subject] in [Background], [Background Details], [Lighting], [Camera Angle]
For example: "Photorealistic, an old man sitting on a wooden bench in a quiet autumn park, surrounded by fallen leaves, soft morning light, eye-level shot."
Formulas containing text:
An image of [subject] with the text "[text content]" written on it, [describe text style]
For example: "A cinematic movie poster for a film called 'Cybernetic Dawn', featuring a cyborg looking over a futuristic city at night. The text 'Cybernetic Dawn' is in a bold, glowing neon font."
4. Some advanced examples
Character Creation: "Concept art of a female space pirate, wearing futuristic armor with glowing blue accents, holding a laser pistol, determined expression, standing on the deck of a spaceship, cinematic lighting."
Landscape: "A breathtaking landscape painting of Ha Long Bay, Vietnam, at sunset. Limestone karsts rising from the emerald water, traditional junk boats sailing peacefully. The sky is a mix of orange, pink, and purple hues. Style of a romanticism painting."
Create an advertising image: "A high-quality product photograph of a new brand of coffee beans in a minimalist package. The package is dark brown with elegant gold typography that says 'Morning Ritual'. The bag is placed next to a steaming cup of coffee on a rustic wooden table."
By mastering the above prompt writing techniques, you can turn Imagen 4 into a powerful assistant, unleashing your creativity and creating unique, impressive and professional visual works. Start experimenting and explore the limitless potential of this powerful AI tool.
