What Are Prompts and Why Are They Essential in AI Image Generation?

In the world of AI-generated images, the word “prompt” appears everywhere. No matter which model you use—Midjourney, Flux, Stable Diffusion, or your tool Flux2to2—the prompt determines the final result.

This article explains what prompts are, why they matter, and how to write them effectively.

01｜What Is a Prompt?

A simple definition:
👉 A prompt is the instruction you give the AI to create an image.

It can be short:
“A cat sitting on a chair.”
“A beach under blue skies and white clouds.”

Or more detailed:
“A cinematic street scene at dusk, warm neon reflections on wet pavement, shot with a 35mm lens.”

Clearer prompts = better images.

02｜What Do Prompts Control?

Prompts directly affect:

Subject
Style
Lighting
Mood
Composition & lens type

A prompt is essentially your “visual direction.”

03｜A Simple Prompt Structure

Use this for almost any image:
Subject + Descriptive details + Style/Mood + Lighting + Composition

Example:
“A girl in a black jacket, standing in neon-lit streets at night, cinematic close-up.”

04｜Common Prompt Mistakes

❌ Too vague
❌ Conflicting instructions
❌ Missing key details
