Guide to Perfect AI Images#

This guide explains how to create compelling images for your media work with the professional image generators FLUX.2 Pro from Black Forest Labs and Gemini 3 Image Pro. From social media visuals and product images to infographics, you’ll find all the essential basics and practical examples here.

Prompting Basics #

Prompt Structure #

FLUX.2 Pro and Gemini 3 Image Pro (Nano Banana Pro) work best with a clear structure. Use this framework for consistent results:

Subject + Action + Style + Context

Subject: The main focus (person, object, scene)
Action: What the subject is doing or its pose
Style: Artistic approach, medium, or aesthetic
Context: Setting, lighting, time, mood

Example:

A businesswoman in a suit, confidently presenting at a whiteboard,
professional business photography, modern office with glass walls
and warm daylight

Geschäftsfrau präsentiert im modernen Büro

Word Order Matters #

FLUX.2 gives more weight to the elements at the beginning of your prompt. That’s why you should place the most important elements first:

Main subject
Most important action
Key style
Essential context
Additional details

The Right Prompt Length #

Length	Words	Use case
Short	10-30	Quick concepts, style exploration
Medium	30-80	Ideal for most projects
Long	80+	Complex scenes with many details

For most use cases in editorial teams and agencies, 30-80 words are ideal.

Important

No negative prompts!

FLUX.2 does not support negative prompts. Always describe what you do want, not what you don’t want.

❌ Wrong: “no blur, no people in the background”

✅ Correct: “sharp image, empty background, isolated”

Prompting in Your Own Language #

FLUX and Gemini are multilingual. You can prompt directly in German—the model understands your instructions. For culturally authentic results, it is even recommended to use the language that fits the context:

A cozy Bavarian inn at Christmas time,
rustic wooden furniture, candlelight, guests toasting with beer steins,
warm atmosphere, traditional decorations

Gemütliches bayerisches Wirtshaus mit Gästen

Text in Images #

Text in Quotation Marks #

You can include readable text in images. This works with both FLUX.2 and Gemini Pro. In experiments, Gemini Pro has proven to handle longer text better.

Use quotation marks to specify the exact text:

A shop sign with the text "OPEN NOW" in green
neon letters above a wooden door

Grünes Neonschild mit Text JETZT GEÖFFNET

Describing Text Design #

For optimal results, describe:

Placement: Where the text appears (e.g. “top center”, “on the banner”)
Style: Type of typography (e.g. “elegant serif font”, “bold industrial lettering”, “handwritten script”)
Size: Relative size (e.g. “large headline”, “small subtitle”)
Color: Ideally with a HEX code (see next section)

Example for an advertising poster:

Modern advertising poster for a summer sale,
large headline "UP TO 50% OFF" in bold white type,
subtitle "excluding pet food" in an elegant serif font,
bright yellow background with geometric shapes,
professional graphic design

Colors and Corporate Identity #

Using HEX Color Codes #

For precise color control—especially important for CI-compliant designs—FLUX.2 supports HEX color codes.

Syntax:

The background uses the hex color #1A5F7A
The logo appears in hex #FF6B35

Example for brand colors:

Elegant business card on a marble background,
the text "CREATIVE STUDIO" in hex color #2E4057,
below it the text "24/7" smaller in bold type, hex color #048A81,
minimalist design, white cardstock.

Creating Color Gradients #

For color gradients, describe the start and end color:

An abstract background image with a gradient,
starting with hex #667eea in the top left,
transitioning to hex #764ba2 in the bottom right,
smooth transitions, modern and clean

Tip

Tip for CI-compliant designs:

Always link HEX codes to specific objects. Vague instructions like “use #FF0000 somewhere” lead to inconsistent results.

Photography Style and Camera Settings #

For photorealistic images, specific camera references deliver the best results. Here you’ll find the most important terms for your media work.

Camera Models and Lenses #

Term	Effect
Shot on Sony A7IV	Modern, sharp digital aesthetic
Canon 5D Mark IV	Professional DSLR quality
Hasselblad X2D, 80mm	Medium-format look, premium quality

Shot on Kodak Portra	Analog film aesthetic, natural grain
2000s digicam style	Early digital camera aesthetic, slight noise
80s vintage photo	Film grain, warm color cast, retro

Image Compositions #

Term	Effect
Rule of thirds	Subject placed on third lines, dynamic
Golden ratio composition	Golden ratio, harmonious image layout
Centered composition	Subject centered, symmetrical, calm
Symmetrical composition	Mirrored arrangement, balanced
Shallow depth of field	Shallow depth of field, blurred background

Leading lines	Lines lead to the main subject, creating depth
Frame within a frame	Natural frame around the subject, stronger focus
Negative space	Lots of empty space, subject appears isolated
Low angle shot	Low perspective, subject appears powerful
High angle shot	High perspective, subject appears small
Eye level shot	Eye level, neutral and natural

100mm macro	Product details, close-ups
70-200mm	Compression, isolates the subject from the background

Camera Angles #

Angle	Effect
eye level	Neutral, at eye level, authentic
high angle	From above, makes the subject seem smaller/more vulnerable
low angle	From below, makes the subject seem powerful/heroic
overhead shot	Directly from above (e.g. for flat lays)
dutch angle	Tilted, creates dynamism or tension
aerial view	Drone shot, shows large areas
over the shoulder	Over the shoulder, for dialogue scenes

JSON-Structured Prompts #

For complex scenes with many elements, you can use JSON-structured prompts. This allows precise control over individual image components.

When should you use JSON?#

Production workflows with a consistent structure
Automated image generation
Complex scenes with multiple subjects
When individual elements should be iterated independently

    }
  ],
  "style": "Artistic style",
  "color_palette": ["#HEX1", "#HEX2", "#HEX3"],
  "lighting": "Lighting description",
  "mood": "Emotional tone",

Aspect Ratios #

Choose the right format depending on the intended use:
