Google Imagen 4 is a text-to-image model for polished product visuals, editorial scenes, and campaign concepts. If you are learning how to use Imagen 4, start with a clear production goal, write a structured prompt, choose the right Imagen variant, and review the result against the way you plan to publish it.
This guide explains a practical Imagen 4 workflow inside OpenVideoMaker. The current Imagen 4 AI Image Generator page is designed for text prompts, so the prompt should carry the subject, composition, lighting, style, and publishing intent.
What is Imagen 4?
Imagen 4 is a Google AI image generator focused on text-to-image creation. The OpenVideoMaker page includes Imagen 4, Imagen 4 Ultra, and Imagen 4 Fast so you can compare a polished pass with faster prompt exploration.
Use Imagen 4 when the brief needs clean composition, controlled lighting, and a production-ready still. For projects that need reference-image editing, compare GPT Image, Seedream, or Kling AI Image Generator instead.
How to use Imagen 4 step by step
1. Define the image job
Write down the subject, audience, channel, and purpose before opening the generator. A product hero image, editorial illustration, social thumbnail, and ecommerce listing image each need a different composition. Naming the final use case helps the model prioritize useful details instead of producing a generic scene.
2. Describe the subject and composition
Start with the main subject, then explain where it sits in the frame. Include the camera angle, crop, negative space, background, and visual hierarchy. If the image needs room for headline copy, say where the clear space should remain. If the product must stay centered, state that directly.
3. Add lighting, material, and style
Use concrete visual language instead of stacking broad adjectives. Describe soft window light, hard midday shadows, brushed metal, transparent glass, matte paper, editorial color grading, or clean commercial photography. These details give Google Imagen 4 a stronger visual direction than a prompt that only says “make it beautiful.”
4. Choose an Imagen variant
Use Imagen 4 Fast when you are testing several prompt directions quickly. Use Imagen 4 for a balanced production pass. Use Imagen 4 Ultra when the composition is already working and the final still needs a stronger quality-focused attempt. The best variant depends on the review stage, not simply on the largest available setting.
5. Match the output to the channel
Choose the aspect ratio and resolution based on where the image will appear. A 16:9 frame works for a website hero or YouTube visual, while 1:1 or 4:5 can be better for a product card or social post. Check the crop before you approve the image, especially when the subject has important edges or packaging details.
6. Review before publishing
Check subject accuracy, composition, material detail, lighting consistency, background distractions, and text readability. If the output contains a brand name, product claim, person, or recognizable property, complete the appropriate human, legal, and brand review before publishing.
Imagen 4 prompt template
Use this structure for a first pass:
Create a [image type] for [audience or channel].
Subject: [main product, person, place, or object]
Composition: [framing, camera angle, placement, negative space]
Environment: [location, background, time of day]
Lighting and material: [light direction, surface, texture, reflections]
Style: [commercial, editorial, photoreal, illustrated, cinematic]
Constraints: [ratio, clean edges, no logos, no unreadable text, publishing intent]
The template is intentionally modular. If the first output is too generic, improve the subject or material line. If the image is hard to crop, clarify the composition and negative space. If the mood is wrong, adjust lighting and style instead of rewriting every part of the prompt.
Example Imagen 4 prompts
Product hero image
Create a premium ecommerce hero image for a skincare landing page. Subject: a matte white glass serum bottle with a simple silver cap, centered on a pale stone surface. Composition: front three-quarter view with generous clean space on the left for headline copy. Environment: warm minimalist studio with a soft beige background. Lighting and material: diffused window light, subtle glass reflections, realistic stone texture. Style: polished commercial product photography. Constraints: 16:9 composition, no logo, no unreadable text, clean edges.
Editorial scene
Create an editorial image for a travel magazine. Subject: a small red train crossing a green mountain valley after light rain. Composition: wide landscape frame with the train in the lower third and layered mountains in the distance. Environment: cool morning mist, wet grass, soft overcast sky. Lighting and material: natural atmospheric light with realistic water and foliage detail. Style: cinematic editorial photography. Constraints: calm composition, no text, no logos, strong depth.
When to use another model
Imagen 4 is a strong fit when the prompt is the main source of visual direction. If the project starts from several reference images, Seedream or Kling AI Image Generator may be a better next step. If the image needs editing, controlled reinterpretation, or a product reference to stay stable, compare GPT Image.
For a broader workflow, start at the AI Image Generator hub, then choose the model based on the input type, output channel, quality target, and review speed. Once the still is approved, move to Image to Video or Seedance when the campaign needs motion.
FAQ
Can I upload reference images to Imagen 4?
The current OpenVideoMaker Imagen 4 workflow is text-only. If you need reference-guided editing or multi-image composition, use a model page that exposes reference image input, such as GPT Image, Seedream, or Kling AI Image Generator.
Which Imagen 4 variant should I choose?
Use Fast for prompt exploration, Imagen 4 for a balanced generation pass, and Ultra when the direction is already approved and the final image needs a higher-quality attempt. Always confirm the current settings and credit estimate in the generator.
Is Imagen 4 free?
Access, credits, and provider terms depend on the current OpenVideoMaker plan and model availability. Check the live generator and pricing information before planning a production workflow around a specific variant.
How do I write better Imagen 4 prompts?
Name the subject, composition, environment, lighting, materials, style, and constraints. Keep the first prompt focused on one visual job, then change one variable at a time after reviewing the result.
Final checklist
- Define the publishing channel before generating.
- Describe composition and negative space, not only style.
- Choose Fast, standard, or Ultra based on the workflow stage.
- Check crop, materials, background, and text before approval.
- Review rights, brand rules, and provider terms before publishing.
