Guide to Perfect AI Images#
This guide explains how to create compelling images for your media work using the professional image generators FLUX.2 Pro by Black Forest Labs and Gemini 3 Image Pro. From social media visuals and product images to infographics, youâll 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 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
Word Order Matters#
FLUX.2 gives more weight to the elements at the beginning of your prompt. So place the most important elements first:
Main subject
Most important action
Defining 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 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 donât want.
â Wrong: âno blur, no people in the backgroundâ
â Correct: âsharp image, empty background, isolatedâ
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, itâs 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
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
Describe the Text Design#
For the best results, describe:
Placement: Where the text appears (e.g. âtop centerâ, âon the bannerâ)
Style: The type of typography (e.g. âelegant serif fontâ, âbold industrial letteringâ, âhandwritten scriptâ)
Size: Relative size (e.g. âlarge headlineâ, âsmall subheadingâ)
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
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.
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
Tip
Tip for CI-compliant designs:
Always link HEX codes to specific objects. Vague instructions like âuse #FF0000 somewhereâ lead to inconsistent results.
Photography Style and Camera Settings#
For photorealistic images, specific camera references deliver the best results. Here youâll find the most important terms for your media work.
Camera Models and Lenses#

When should you use JSON?#
Production workflows with a consistent structure
Automated image generation
Complex scenes with multiple subjects
When individual elements need to be iterated independently
