Photorealistic Styles

FLUX generates photorealistic images from natural language. Reference specific eras, cameras, and film stocks for distinctive looks.
StyleKey Descriptors
Modern Digital”shot on Sony A7IV, clean sharp, high dynamic range”
2000s Digicam”early digital camera, slight noise, flash photography, candid, 2000s digicam style”
80s Vintage”film grain, warm color cast, soft focus, 80s vintage photo”
Analog Film”shot on Kodak Portra 400, natural grain, organic colors”

Soaking wet tiger cub taking shelter under a banana leaf in the rainy jungle, close up photo

For photorealism, specify camera models, lenses, and film stocks. “Shot on Fujifilm X-T5, 35mm f/1.4” produces more authentic results than just “professional photo.”

​
Camera and Lens Simulation

Be specific about camera settings for authentic results: 
Shot on Hasselblad X2D, 80mm lens, f/2.8, natural lighting

Canon 5D Mark IV, 24-70mm at 35mm, golden hour, shallow depth of field

Art Styles & Illustration

FLUX handles a wide range of artistic styles beyond photorealism. Name the style specifically and describe its visual characteristics. Style fusion — Combine two styles with a unifying palette:

Style Fusion Example

“Ancient Greek marble statue precision and anatomical detail, infused with cyberpunk neon lighting, holographic overlays, and electric blue/magenta glow effects, set against dark futuristic environments”
Style + mood annotations — Add explicit tags at the end of your prompt for consistent aesthetics: 
[Scene description]. Style: Country chic meets luxury lifestyle editorial.
Mood: Serene, romantic, grounded.

[Scene description]. Shot on 35mm film (Kodak Portra 400) with shallow
depth of field — subject razor-sharp, background softly blurred.
1990s editorial
Surreal interior
Golden hour silhouette

Lighting

Lighting has the greatest single impact on output quality. Describe it like a photographer would — “good lighting” is not enough. What to describe:
  • Source: natural, artificial, ambient
  • Quality: soft, harsh, diffused, direct
  • Direction: side, back, overhead, fill
  • Temperature: warm, cool, golden, blue
  • Interaction: catches, filters, reflects on surfaces
Rembrandt lighting (45° key light) — triangle of light on the face for dramatic portraits:“Portrait with Rembrandt lighting, key light at 45 degrees, dramatic chiaroscuro effect”Split lighting (90° side light) — half-face illuminated for high contrast:“Artistic portrait, split lighting, strong side illumination, dramatic contrast”

Window light = soft, even illuminationGolden hour = warm and softBlue hour = cool and moodyOverhead artificial = harsh and dramatic

Chiaroscuro — high contrast light/shadow for drama:“Film noir detective scene, single practical desk lamp, strong chiaroscuro lighting”Practical lighting — visible light sources in scene for realism:“Cyberpunk street scene, neon signs and LED strips providing atmospheric lighting”

Text in Images

FLUX handles text well when prompted correctly. Use this three-step approach:
1

Enclose in Quotation Marks

Use quotes for exact text: "COFFEE SHOP" or "Est. 1952"
2

Describe Placement

Specify where text appears: “The text ‘OPEN’ appears in red neon letters above the door”
3

Specify Font Style

Name the style: “elegant serif typography” or “bold industrial sans-serif lettering”
'Open' neon sign

A Entry of a Sushi Restaurant, The text 'OPEN' appears in red neon letters above the door

​
Text Rendering Tips

  • Front-load text descriptions for better accuracy
  • Use quotation marks around exact text you want rendered
  • Describe color and effects: “red neon letters”, “gold serif lettering”, “chalk on blackboard”
  • Use hex codes for brand-precise colors: “The logo text ‘ACME’ in color #FF5733”
  • Keep text short — long strings are harder to render accurately
  • Specify font character: serif = traditional/formal, sans-serif = modern, script = elegant, display = bold/impactful
