What a Midjourney prompt is, the four core principles, and the seven details worth specifying.

What is a Prompt?

A prompt is the text you give Midjourney to describe the image or video you want. It can be a single word or a full phrase — the more deliberate your wording, the more distinctive the result.


Core Principles

1. Short & simple

Short prompts usually work best. Long lists of instructions confuse the model. Think of it as a quick snapshot of your idea rather than a brief.

Show me a picture of lots of blooming California poppies, make them bright vibrant orange, and draw them in an illustrated style with colored pencils

2. Word choice matters

Use precise synonyms. "Gigantic" or "enormous" carries more information than a vague "big".

3. Be specific with numbers

Plurals are vague. Say "three cats" instead of "cats", or use a collective noun like "flock of birds".

4. Focus on what you want

Negative phrasing backfires — asking for a party with "no cake" can still produce a cake. Use the --no parameter to exclude things instead.


Prompt Length

Short prompts let Midjourney's default style fill the gaps — more variety, less control. Longer prompts give you control but reduce surprise. Include only the details that actually matter to you.
