Midjourney remains a favorite for stylized, high-quality images when you learn its prompt grammar. This beginner tutorial covers access, basic parameters, composition control, and a repeatable workflow for blog heroes and social creatives.

What you will learn
- Start a project and understand the prompt → grid → upscale flow
- Control aspect ratio, stylization, and variety
- Build a style reference board for brand consistency
- Export assets sized for web (see your theme’s recommended hero dimensions)
Prerequisites
- Active Midjourney subscription (check official site for current access: Discord and/or web UI)
- One brand adjective list (e.g. “minimal, blue accent, soft light”)
- Lesson 1 completed if you also write captions with ChatGPT
Step 1: Interface basics
Regardless of UI (Discord bot or web), the loop is:
- Prompt — describe subject + medium + lighting + mood
- Grid — four variations; pick the best direction
- Upscale / Vary — refine winner (subtle vs strong)
- Download — PNG for design; compress for web
Keep a prompt log spreadsheet: prompt text, seed (if shown), version, rating 1–5.
Step 2: Prompt structure for beginners
Use this order: subject → environment → style → lighting → camera
Example:
A Vietnamese coffee shop interior, morning light through windows, two professionals with laptops, editorial photography, shallow depth of field, warm tones, no text overlay
Add negatives when supported: no watermark, no distorted hands.
Step 3: Key parameters (concepts)
Parameter names evolve — always check Midjourney docs. Concepts you should know:
| Concept | Purpose |
|---|---|
| Aspect ratio | --ar 16:9 for blog heroes, 1:1 for Instagram |
| Stylize | Higher = more artistic interpretation |
| Chaos | Higher = more surprising compositions |
| Seed | Reproduce a composition direction |
Exercise: Generate the same prompt at --ar 16:9 and 1:1; note cropping differences.
Step 4: Style consistency
- Save 5–10 on-brand winners to a mood board.
- Reuse phrasing for lighting and palette across posts.
- For characters, use character reference features when available instead of re-describing faces each time.

Step 5: Hands and text pitfalls
AI images still struggle with hands, small text, and logos. Mitigations:
- Frame shots to avoid prominent hands
- Add titles in Figma/Canva after generation
- Use higher upscale before detecting artifacts
Step 6: Web publishing workflow
- Generate at 2× needed width when possible
- Export WebP or JPEG (~120–200 KB target for heroes — tune for your CDN)
- Write descriptive alt text for accessibility and SEO
- Credit policy: follow Midjourney terms and your site’s disclosure rules
Common mistakes
- Prompting like a Google search (
nice picture of AI) - Changing ten variables at once (you cannot learn cause and effect)
- Using copyrighted character names in prompts
- Skipping alt text on blog heroes
