Mastering Flux.1 & Midjourney v6.1: Complete Prompt Engineering Guide (2026)

Introduction to Flux.1 and Midjourney v6.1

Flux.1 and Midjourney v6.1 are two of the most capable image models available. Flux.1 excels at photorealism and plain-English instructions, while Midjourney shines at stylised, painterly and cinematic results.

In this guide you will learn how to structure prompts for each model, which parameters matter, and how to get consistent output from one generation to the next.

The Anatomy of a Great Prompt

A well-built prompt describes the subject, the environment, the lighting, the style and the camera. Order matters: models give more weight to words near the start.

Negative prompts, where supported, help remove unwanted artefacts such as extra fingers or watermarks.

Prompt Example (Flux.1)

/imagine prompt: [Subject], [Environment], [Lighting], [Style], [Camera Angle], [Details]

Advanced Parameters and Techniques

Midjourney offers –stylize, –chaos, –weird and –sref. Flux.1 is controlled mostly by guidance scale and step count. Start with defaults, change one value at a time and keep notes.

• Use –sref to reuse a visual style across a series.
• Lower Flux guidance (2.5–3.5) for natural skin and light.
• Fix the seed while you tune wording.

Real Prompt Examples

Copy the template below, replace the bracketed parts and iterate. Small edits to lighting and lens give the biggest jumps in realism.

Tips for Better Results

Keep a library of prompts that worked, label them by subject and note the model version. When a model updates, re-test your favourites; a prompt that was perfect on v6 may need a tweak on v6.1.
