Features of Flux 1.1 Pro

Flux 1.1 Pro focuses on simplicity and efficiency. It includes parameters like:
- Width and Height
- Number of Steps for refinement
- Seed Customization for reproducible results
While these settings offer control, the real magic lies in Flux 1.1 Pro’s ability to generate realistic images that feel like they were captured with a high-end camera.
Common Pitfalls: The AI Look
Many AI tools produce images that scream “generated” due to:
- Overly smooth or shiny skin.
- Unrealistic bokeh effects.
- Perfect lighting and symmetry.

Flux 1.1 Pro addresses these issues by introducing realistic grain, imperfect lighting, and authentic textures to its outputs.
Pro Tip: Using Image File Formats for Realism
A breakthrough trick for Flux 1.1 Pro is mimicking camera-generated file formats in your prompts. This unique approach results in natural-looking photos that avoid the AI-generated feel.
How to Use the File Format Trick
- Understand Image File Formats: Real cameras often use file names like
IMG_001.jpeg
or formats like.cr2
(used by Canon cameras). - Incorporate the Format into Your Prompt:
- Example:
IMG_1016.cr2
- Add a simple description, like
a woman
.
- Example:
- Avoid Overloading the Prompt: Use only 2–3 words for the description to maintain realism.
Example

This trick introduces the grain, imperfections, and lighting variations seen in actual camera photos.
Experimenting with the Trick
Initial Test: A Woman in a Café
Result: An overly polished image with artificial lighting.
Improved Prompt: File Format Trick

Key Takeaway: The file format trick dramatically enhances realism by mimicking the imperfections of real photography.
Testing Variations
Changing the digits in the file format can produce varied results:


Pro Tip: Experiment with different digits to discover unique results.
Using Alternative Prompts
If the file format trick feels complex, you can simplify your prompt:
Using “Selfie.jpg”

Why It Works: Adding .jpg
or .png
signals the model to mimic photography norms, producing images with authentic qualities.
Why Flux 1.1 Pro Stands Out
- Unmatched Realism: Avoids the overly polished AI look.
- Efficient Parameters: Minimal settings with maximum control.
- Flexibility: Works across various platforms like Together.ai and FAL.com.
- Innovative Tricks: Incorporating file formats into prompts adds depth and authenticity.
Final Thoughts
Flux 1.1 Pro is a game-changer for generating realistic AI images. Whether you’re creating portraits, animal images, or candid shots, its unique ability to mimic real photography makes it an essential tool for any AI artist.
