Midjourney: A Complete Beginner's Guide to AI Image Generation
Midjourney has established itself as one of the most capable AI image generation tools available—producing photorealistic images from text prompts with a level of detail and quality that still surprises experienced users.
A simple prompt like "Japanese woman in a white shirt" generates images indistinguishable from professional photography, with fine details like individual strands of hair and precise fabric textures rendered accurately. Beyond static images, Midjourney now generates videos up to 21 seconds long from any generated image, making it useful for social media content, business materials, and marketing assets.
Core Features
- High-fidelity photorealism: Extremely detailed rendering of faces, textures, lighting, and backgrounds
- Japanese-language prompts: Supported with quality comparable to English prompts
- Video generation: Up to 21-second clips with Low Motion and High Motion speed options
- V7 model: Learns user style preferences over time for more consistent results
Getting Started
Midjourney is available via both a web interface and Discord. The web version is recommended for new users—it's more intuitive and receives new features first.
Registration:
- Search for "Midjourney" and visit the official site
- Click the sign-up button in the lower left
- Log in with a Google or Discord account
Plans (monthly pricing, 20% discount with annual billing):
- Basic: ~$10/month, approximately 200 image generations
- Standard: ~$30/month, 15 hours of fast generation + unlimited relaxed mode
- Pro: ~$60/month, adds Stealth Mode (images and prompts kept private)
- Mega: ~$120/month, for high-volume users
For business use requiring confidentiality, Pro plan is necessary—on lower plans, generated images and prompts are publicly visible.
Generating Images
The workflow is straightforward: type a prompt in the chat field, submit, and four variations are generated within seconds. You can then:
- Upscale your preferred variation
- Generate new variations from any result
- Add elements progressively ("add red flowers," "softer lighting") to refine toward your target
- Convert any image to a video with the Animation button
Pro tip: When prompts don't produce the desired result, tools like ChatGPT can help refine the wording before submitting to Midjourney.
Video Generation
The animation feature converts static images into short video clips:
- Generate your image
- Click the Animation button
- Choose Low Motion (subtle movement) or High Motion (more dynamic)
- Use "Extend Video" to chain multiple clips into sequences up to 21 seconds
How Midjourney Compares
Against Adobe Firefly and ChatGPT's image generation, Midjourney generally produces more photorealistic results with better compositional coherence. Firefly's strength is copyright safety for commercial use; ChatGPT's DALL-E integration is more conversational. Midjourney leads on pure visual quality for most use cases.

Google's Nano Banana (Gemini 3 Flash Image): Spatial Understanding and Multi-Image Synthesis
Google's "Nano Banana"—officially Gemini 3 Flash Image—appeared on the LM Arena leaderboard under its codename before the formal announcement. The name stuck because the model itself made an impression: it demonstrated capabilities that previous image generation systems couldn't match.
What Makes Nano Banana Different
Nano Banana operates differently from text-to-image generators like Midjourney. It's built for image editing and transformation—taking an existing image and modifying it according to natural-language instructions, while preserving specific elements the user wants to keep unchanged.
Four capabilities stand out:
1. Spatial understanding
Nano Banana can re-render a scene from a different viewpoint. Input an image of an intersection, ask for an overhead view, and the model reconstructs the buildings, signage, and street layout from that new angle—maintaining architectural details that weren't visible in the original image. This requires genuine spatial reasoning, not just style transfer.
2. Consistency preservation
When changing one element of an image—say, swapping a clothing outfit—Nano Banana keeps the subject's face, hands, and other details consistent. In head-to-head testing, ChatGPT's image editing changed the subject's face when modifying clothing. Nano Banana maintained facial characteristics while accurately executing the clothing change.
3. Text rendering
Accurate text within images has been a persistent weakness of image generation AI. Nano Banana renders English text in images cleanly. Japanese text rendering still has room for improvement, but the English performance is notably stronger than previous models.
4. Multi-image synthesis
Nano Banana can accept multiple images as input and synthesize them into a single output. In demonstrations, combining a personal photo with a holiday message produced a postcard-style result with the text "Merry Christmas" rendered cleanly in the upper right—a task that would have required multiple steps in traditional editing software.
Practical Applications
| Use Case | What Nano Banana Enables |
|---|---|
| Product photography | Reangle shots without reshooting |
| Social media | Personalized cards combining photos and text |
| Web design | Visual layout iteration with browser rendering feedback |
| Fashion | Visualize clothing on existing photos of models |
| Marketing | Seasonal variations of base images |
Current Limitations
- Japanese text rendering needs improvement
- Complex spatial reconstruction can produce artifacts at high detail levels
- As with all image AI, outputs require review before commercial use
The Bigger Picture
Nano Banana points toward a near future where image editing doesn't require knowledge of Photoshop layers, masks, or blend modes. Users describe what they want in plain language, and the model executes it. For non-designers, this removes a significant barrier; for professional designers, it accelerates iteration.
