Prompt-Leitfaden für Seedream
TARGET MODEL: Seedream (ByteDance image — generation and editing are one unified model). The prompt is the whole instrument: write a finished CAPTION in prose, not tags.
Regeln, die gelten müssen
- Lead-weighting is the exploitable behavior: concepts mentioned EARLIER weigh more. The first clause is the hero — put what must survive first, negotiable detail last.
- The formula, left-to-right as priority order: Subject → Scene/Setting → Composition & Framing → Style → Lighting & Atmosphere → Camera/Lens.
- Length: 30-100 words is the sweet spot (hard ceiling ~600); more words only when they add a decision — padding dilutes the lead.
- Kill noise tokens: "masterpiece, best quality, 8K, ultra-detailed, trending" — delete them.
- Aspect ratio is a parameter, never prose — do not write "16:9" or frame ratios into the caption.
- On-image copy goes in "double quotes", in the TARGET SCRIPT (actual glyphs — "静かな庭", never romanized). Unquoted text renders as the idea of a sign, not the words.
- Editing REGENERATES the entire frame — "keep X unchanged" is guidance to imitate, never a pixel lock. Never promise preservation of a real capture.
Was am besten funktioniert
- Every noun carries a modifier — resolve the subject to something a camera could find: age, hair, expression, wardrobe, material. "A woman" is a stock face.
- State shot scale ("medium shot", "close-up", "overhead perspective"); stronger still, name the focal point inside the scene ("his hands are the focal point") and put the camera in space ("taken from 3000 feet").
- Name geometry ("symmetrical composition", "rule of thirds", "foreground detail with blurred background") and anchor every element with prepositions ("on the left side", "between them", "arranged left to right") — ambiguity is the only thing that drifts.
- Photoreal fork: "photorealistic rendering / ultra-detailed / commercial quality" produces a clean CGI look — right for products, wrong for faces. For a photograph, describe a CAPTURE plus a genre ("editorial photography", "documentary", "street photography").
- Camera report as observation: focal length as grammar (24-35mm environmental, 50-85mm portrait, 100-200mm compression); aperture by its effect ("the bokeh turns harbor lights into perfect circles"); shutter as motion ("1/8000 freezes", "30-second exposure trails the lights").
- Pair a film stock with a color line: "Kodak Portra 400, warm color cast, visible film grain" beats the stock name alone; push language works ("expired Portra 800, pushed two stops, halation, lifted blacks").
- Motivated light: direction + quality + color, optionally a named recipe ("warm tungsten key from frame-left, cool cyan neon rim"; "chiaroscuro", "Rembrandt", "Vermeer lighting").
- Fight plastic skin texture-forward and positive: "weathered face", "sun-kissed skin", "visible pores and fine lines", "matte skin", "no beauty retouching", "visible film grain" — never the phrase "realistic skin".
- Style: ONE named anchor, set twice as bookends — a register word opens the caption, a finishing tag closes it. Director and stock references are native ("in the manner of Deakins", "Wes Anderson palette", "film noir"). Blend at most one movement + one technique; reach for a style's keyword cluster ("soft edges, translucent layers, paper texture") when the bare name renders timid.
- Typography is the signature strength: give quoted copy a surface and a treatment ("neon sign reading …", "engraved brass plate", "handwritten chalk"); spec type like a designer — character, weight, case, color, and a grid position ("top-left", "along the bottom edge"). Keep each line ~3-5 words; numerals, currency and dates are copy too. Dense body copy or fine print (when it is NOT user-quoted verbatim copy): cut the word count and describe it by role rather than transcribing it. Posters: name the medium, then stack each line top-to-bottom with copy + size word + anchor.
- Sequential sets: trigger with "series", "set", "sequence", a numeric count, or an explicit grid ("2x2 storyboard grid", "three-view drawing"); copy the character description VERBATIM between panels; declare each frame's copy, shot scale and vantage so the set reads as one designed system.
