Core Prompting Principles

1. Element Prioritization

Seedream 4.5 prioritizes elements that appear earlier in your prompt. Always place your main subject or focal point at the beginning of your description.

Good Example:

"A majestic white tiger resting on ancient temple ruins, golden hour lighting, mystical atmosphere, photorealistic, 8k detail"

Less Optimal:

"Golden hour lighting, mystical atmosphere, photorealistic, 8k detail of a majestic white tiger resting on ancient temple ruins"

2. Be Explicit and Detailed

Clearly list the subject, action, style, lens/camera, time of day, and desired color palette. The more specific you are, the better Seedream understands your vision.

Prompt Formula: [Subject] + [Action/Pose] + [Setting/Background] + [Style] + [Lighting] + [Camera/Technical] + [Mood/Atmosphere]

Example:

"Young woman with flowing auburn hair, standing on a cliff edge, overlooking misty mountains, portrait photography, dramatic side lighting, shot on 85mm lens, shallow depth of field, contemplative mood, cinematic"

Text Rendering in Images

Seedream 4.5 excels at typography and text rendering. Here's how to get the best results:

Best Practices for Text

1. Use quotes around the desired text: "WELCOME HOME"
2. Specify font style: bold, serif, handwritten, neon sign, graffiti
3. Define placement: centered, top of image, on the banner
4. Keep it short: 1-10 words work best for consistent results

Example Prompts:

"Vintage coffee shop sign reading 'FRESH BREW' in bold serif font, rustic wooden background, warm lighting"

"Neon sign glowing 'OPEN 24/7' in pink and blue, rainy city night, reflections on wet pavement"

"Birthday cake with 'Happy 30th' written in elegant cursive icing, pastel colors, soft studio lighting"

Using Reference Images

Seedream 4.5 supports 1-3 reference images to anchor identity and style for consistent results.

When to Use Reference Images

• Character consistency across multiple scenes
• Product photography with specific items
• Style matching to a reference artwork
• Face preservation for portraits

Tips for Reference Images

1. Use high-quality, well-lit reference images
2. Keep backgrounds simple when focusing on subjects
3. Match the lighting direction in your prompt to the reference
4. Use descriptors like "same person" or "matching style" in your prompt

---

Negative Prompts

Explicitly state elements you want to avoid:

Common Negative Prompts:

"no text, no watermarks, no extra limbs, no blurry, no distortion, no cropped, no low quality"

For Portraits:

"no deformed faces, no asymmetrical eyes, no extra fingers, no unnatural skin texture"

---

Multi-Image Workflow Consistency

For projects requiring consistent elements across several images:

Consistency Techniques

1. Use the same seed for related renders
2. Keep camera descriptors consistent: "85mm portrait, softbox, 3/4 view"
3. Use identity anchors: "the same woman with short wavy hair, green jacket, scar on left eyebrow"
4. Fine-grained preservation: "preserve facial structure, change hair color only"
