Prompting Basics#

Prompt Structure#

FLUX.2 Pro and Gemini 3 Image Pro (Nano Banana Pro) work best with a clear structure. Use this pattern 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
GeschĂ€ftsfrau prĂ€sentiert im modernen BĂŒro

Word Order Matters#

FLUX.2 gives more weight to the elements at the beginning of your prompt. So place the most important elements first:

  1. Main subject

  2. Most important action

  3. Defining style

  4. Essential context

  5. 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 lots of detail

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

Important

No negative prompts!

FLUX.2 does not support negative prompts. Always describe what you 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’s 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
GemĂŒtliches bayerisches Wirtshaus mit GĂ€sten

Text in Images#

Put Text in Quotation Marks#

You can include readable text in images. This works with both FLUX.2 and Gemini Pro. In tests, Gemini Pro tends 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
GrĂŒnes Neonschild mit Text JETZT GEÖFFNET

Describe the Text Design#

For the best results, describe:

  • Placement: Where the text appears (e.g. “top center”, “on the banner”)

  • Style: The type of typography (e.g. “elegant serif font”, “bold industrial lettering”, “handwritten script”)

  • Size: Relative size (e.g. “large headline”, “small subheading”)

  • Color: Ideally with a HEX code (see next section)

Example for an advertising poster:

Modern advertising poster for a summer clearance sale,
large headline "UP TO 50% OFF" in bold white lettering,
subheading "excluding pet food" in an elegant serif font,
bright yellow background with geometric shapes,
professional graphic design
Gelbes Werbeplakat mit Rabatt-Text

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-textured background,
the text "CREATIVE STUDIO" in hex color #2E4057,
below it the text "24/7" in smaller bold lettering, hex color #048A81,
minimalist design, white card stock.
Elegante Visitenkarte mit Markenfarben

Creating Gradients#

For 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
Violett-blauer Farbverlauf

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.

  • Automated image generation

  • Complex scenes with multiple subjects

  • When individual elements need to be iterated independently
