Specify the medium, texture, and lighting: a flash snapshot, a grainy night photograph, or an anime poster. Concrete descriptions give more direction than labels such as “aesthetic” or “professional”.

​
Photorealistic Styles

Describe the photograph you want: the era, the camera or film stock, and what that look does to the image (grain, color cast, flash, focus). The layout captions shown here open with one sentence that sets the medium and the look. For photographs, it reads like this: Both were generated from a full caption plus a layout. The quoted sentence is the part that sets the look. The tabs below show more photographic styles, all generated with FLUX 3 Image:
Wet tiger cub under a banana leaf in a rainy jungle

FLUX 3 Image

Name the camera, lens, or film stock instead of writing “professional photo”: “Shot on Fujifilm X-T5, 35mm f/1.4”. Then describe what it looks like: “visible grain”, “a warm color cast”, “slight chromatic aberration at the edges”.

Art Styles & Illustration

FLUX 3 renders a wide range of styles beyond photographs. Name the style specifically and describe its visual characteristics: the FLUX 3 Tokyo poster below opens with “A stylized digital illustration in a flat, graphic anime style, resembling a modern pop-art poster with non-directional, uniform lighting.” These three FLUX 3 Image examples also open the caption with the medium and the style:
  • Tiger poster: “Full-color digital scan of a flat, vertical graphic design poster exhibiting a minimalist, mid-century Japanese aesthetic and a two-dimensional, screen-printed quality.”
  • Character sheet: “Digital illustration character model sheet against a plain white background, featuring clean, thick linework and a color palette of red, green, and cream.”
  • Design categories: “Flat-color digital illustration of a minimalist graphic design presented against a solid black background.”
A plain prompt can set a style too. These FLUX 3 Image results each come from the prompt below them: Style fusion: Combine two styles with a unifying palette. This example was generated with an earlier FLUX model.

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 (documented for FLUX.2 [klein]): Add explicit tags at the end of your prompt for consistent aesthetics:

​
Style from a reference image

When a style is hard to put into words, send an image of it. FLUX 3 Image takes up to 10 references in images; refer to them by position in the prompt. Here, image 1 is the subject and image 2 is the style: The result keeps the temple’s architecture and takes the speckled night sky and textured paper look from image 2. See Multi reference for the request, and Multi-Reference Editing for more style and material transfers.

​
Lighting

Name the light source, direction, and quality. For example, “soft window light from the left” describes more than “good lighting”. 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
The FLUX 3 launch prompts name the source and say what the light does:
  • “lit by harsh, direct camera flash that casts sharp shadows against the background”
  • “A strong spotlight illuminates the center of the stage, casting long, soft shadows across the floor and highlighting the stiff tulle of the costumes”
  • “Dappled natural sunlight filters through the trees, creating bright highlights against earthy brown and deep green shadows”
  • “under flat, even studio-style lighting”
The lighting examples below were generated with an earlier FLUX model.
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”

Exact colors with hex codes

A hex code names an exact color. In this FLUX 3 Image edit, the prompt picks out one bird and gives it a hex value. That bird turns pink and the rest of the flock stays black: Tie each hex code to one named object (“only one bird in the middle”), so the model knows where the color goes.

​
Text in Images

FLUX 3 renders text in images, from one word on a sign to multi-line poster typography and Japanese text. For each block of text, put three things in the prompt:
1

Quote the exact words

Put every string in quotation marks, with the capitalization and punctuation you want: "東京", "Cabin", "LE FESTIVAL DU SOLEIL".
2

Say where it goes

Place each block in the frame: “runs down the left side of the frame”, “At the bottom center, a line of bright text … sits directly above a smaller line of text”.
3

Describe the type

Give weight, case, color, and character: “Large, bold red kanji and katakana characters arranged vertically, featuring distressed, spray-paint-like edges” or “a clean, sans-serif black font”.
For posters, packaging, and signage, give each text block its own box in a layout. To specify placement, quote the words in the box’s desc, and cite the box in the caption where the text belongs. See Describe each element.

​
How the FLUX 3 examples specify text

These four launch-post images were each generated from a caption plus an element table, with one box per text block. The tables below quote the caption for placement and the box desc for the words and type. Open them in the layout explorer to see every box.
Flat anime-style poster: a horned woman with lavender hair on a yellow background, with large red Japanese text on the left and upper right, a red seal, and a small caption at the bottom.

\n inside the quoted string marks a line break. “arranged vertically” sets the reading direction.

​
Short text in a plain prompt

A word or a short line does not need a layout. Quote it and say where it goes, for example a paper poster on the wall that reads "OPEN LATE". These FLUX.2 examples use the same pattern:
'Open' neon sign

​
Text Rendering Tips

  • Use quotation marks around exact text you want rendered, with the case and punctuation you want
  • Mark line breaks and direction: \n inside the quoted text, “arranged vertically”, “arranged in two centered lines”
  • Describe the type: weight, case, color, and texture. A font name works as a comparison: “a bold, white sans-serif typeface reminiscent of Helvetica or Inter”
  • Describe color and effects: “red neon letters”, “gold serif lettering”, “chalk on blackboard”
  • Specify font character: serif = traditional/formal, sans-serif = modern, script = elegant, display = bold/impactful
  • Give each text block its own box when placement matters: see Describe each element
  • Split long text into blocks: one box per line or row, as in the stamp panels
  • Proofread every quoted string in the output before you publish it, especially small print and long lines
