How to Create Photorealistic Images with Seedream 4.0

One practical system for choosing the right subject detail, material, lighting, composition, and output settings—then turning them into repeatable commercial images.

01 · Capabilities and prompt structure

Build the Photograph Before You Add Style

Seedream 4.0 is strongest when the prompt describes a photograph as a set of visible decisions, not a list of vague quality words.

01Core StrengthsStudio-quality consistency

Seedream 4.0 excels at commercial and editorial visual work. Its training on studio photography datasets makes it the most reliable model for tasks where consistent lighting, material detail, and clean composition matter most.

  • Photorealistic textures: skin, fabric, metal, ceramic, glass, liquid — rendered with natural detail and accurate light interaction
  • Commercial studio lighting: key light, fill, rim separation — all controllable through prompt vocabulary
  • Sharp product detail: clean shadow falloff, consistent edge definition, e-commerce-ready backgrounds
  • Editorial portraits: natural skin tone, depth of field control, professional framing
  • Reliable aspect ratios: 1:1, 3:2, 9:16, 16:9 — all output cleanly without cropping artifacts
02Prompt Formula & TipsSpecificity beats length

Seedream 4.0 performs best with the formula: [Subject] + [Material/Texture] + [Light Source] + [Surface/Background] + [Camera/Mood]

Keep prompts under 30 words. Specificity beats length.

Material vocabulary that works

  • Surfaces: marble, travertine, dark oak, brushed steel, warm concrete, raw linen
  • Finishes: matte, satin, glossy, frosted, hammered, etched
  • Fabrics: raw silk, cashmere, denim, velvet, linen

Lighting keywords

  • “warm side light from left” — commercial product depth
  • “soft window light” — flattering for portraits
  • “even studio lighting” — clean professional output
  • “golden hour” — warm atmospheric outdoor scenes
  • “rim lighting” — product isolation with edge separation

Avoid

  • Prompts over 40 words (reduces output clarity)
  • Abstract emotion words (“beautiful”, “amazing”) — describe visual properties instead
  • Mixing multiple conflicting styles in one prompt

How Every Prompt Term Shapes the Final Photo

This product example shows why each term exists, what visual property it controls, and what becomes less predictable when it is removed.

premium ceramic bottle, matte glaze, warm side light, travertine surface, 85mm editorial product photo
Subject

Premium ceramic bottle

Defines the object and category. Removing “ceramic” often produces generic plastic or glass packaging.

Material

Matte glaze

Controls highlight behavior. Without the finish, reflections can become glossy and inconsistent.

Light

Warm side light

Creates depth and a directional shadow. “Studio light” alone gives less predictable shape definition.

Surface

Travertine

Anchors the product in a specific commercial environment instead of an undefined backdrop.

Camera

85mm editorial

Reduces wide-angle distortion and signals a polished campaign-style composition.

FAQ

Frequently Asked Questions About Seedream 4.0

Seedream 4.0 is specifically tuned for commercial photography and editorial work. Unlike general-purpose models, it consistently delivers accurate material textures, studio-quality lighting, and sharp product detail from short prompts. It's the go-to model when you need output that looks professionally shot, not obviously AI-generated.
Keep prompts under 30 words for best results. Seedream 4.0 is trained on commercial photography descriptions, which tend to be concise and visual. Describe the subject, material, light source, surface, and camera style. Avoid abstract or emotional language — use specific visual vocabulary instead.
Yes. Seedream 4.0 handles both product and portrait photography. For portraits, specify natural expression, light direction, and background type. Example: "professional portrait, woman in her 30s, soft window light from left, warm skin tone, shallow depth of field, editorial style." Avoid prompts with more than one person unless you want a lifestyle scene.
Yes. You can upload a reference image to guide composition, lighting, or style direction. Seedream 4.0 uses the uploaded image as a visual reference rather than editing it directly. For direct photo editing (background removal, retouching), use GPT Image 2 instead.
Seedream 4.0 supports five aspect ratios: 1:1 (square, ideal for social media), 3:2 (landscape, photography standard), 2:3 (portrait), 9:16 (vertical video/stories), and 16:9 (widescreen/banner). Select the ratio in the generator settings before generating.
Use the same structural formula for every prompt in a series: same surface description, same lighting direction, same camera style. Example: all prompts in a skincare product series should include "soft diffused light, clean marble surface, editorial lifestyle" to maintain visual consistency across all SKU images.
