GPT image2生圖模板

多輪實驗完成的生圖模板(但也不可能盡善盡美)，只需要參考圖和人物名字，即可完成這樣的海報。

測試了生化危機人物，非生化遊戲人物，還有豆包。

低視角仰拍半身黑白海報，自帶一個錨點色。

修改人物名字即可生成海報上隨機小字。

會自動提取參考圖中的主色調形成海報錨點色。

=== USER INPUT ===

CHARACTER_NAME: "Ada"

=== 🔥 PRIORITY SYSTEM (ABSOLUTE) ===

1.

color system (grayscale + single accent)

2.

composition (poster framing)

3.

typography layout

4.

narrative text

5.

HUD readability

6.

material realism

7.

identity

IF CONFLICT: discard environment / props / original lighting FIRST never break grayscale never add secondary colors never let text cover eyes preserve narrative over decoration

=== 🔥 IDENTITY EXTRACTION === use reference image ONLY for: face, bone structure, hair, expression

ignore: environment, pose, lighting, props

=== 🔥 SCENE RESET === pure white seamless studio background soft neutral gradient + subtle ground shadow NO environment NO props

=== 🔥 COLOR SYSTEM (LOCKED) === full true grayscale: skin, hair, background, shadows

NO warm / cool tint NO color bleed

ONLY ONE ACCENT COLOR: → clothing + HUD share same color → high purity, high contrast

=== 🔥 PORTRAIT SETUP === ultra realistic photography visible pores, micro imperfections subsurface scattering + subtle oil sheen

=== 🔥 CAMERA === upper body (chest → head) extreme low-angle (worm’s-eye) 24–28mm wide lens slight perspective exaggeration strong eye contact face = focal point

=== 🔥 LIGHTING === high-key studio + directional key clean facial contrast soft rim separation NO color contamination

=== 🔥 MATERIAL (FABRIC) === luxury satin realism anisotropic highlights micro irregular reflections non-uniform gloss no plastic look

=== 🔥 TITLE SYSTEM === BIOHAZARD (large serif, behind subject) RESIDENT EVIL (secondary side aligned)

depth: character > title > background

rules: title behind head partially occluded by hair no overlap on face

print realism: ink bleed, micro grain, slight aging opacity 85–95%

hair strands break letter edges

=== 🔥 HUD SYSTEM (ENHANCED) === HUD color = accent EXACT match

readability priority: line thickness: 1.2–1.8px (visible, not hairline) high-luminance accent variant (not white)

contrast boost: slight grayscale darkening behind HUD (5–8%)

layer structure: foreground ring (sharp) mid ring (slight blur) background radial noise (faint)

render: crisp core + soft glow halo primary opacity 85–100% secondary 60–75%

optical integration: follows eyeball curvature micro parallax offset slight chromatic aberration reflection visible on cornea subtle light spill on eyelid

ABSOLUTE: HUD must remain instantly readable if conflict → reduce blending BEFORE visibility

=== 🔥 EDITORIAL POSTER === high-end fashion + cinematic hybrid text interacts with silhouette never cover eyes

=== 🔥 NARRATIVE TEXT (ARCHIVE MODE) === all small text = in-universe dossier

structure: HEADER / CODENAME / STATUS / MISSION / LOCATION / CLASS / NOTES / DATA

style: short fragments technical + poetic no full sentences no generic wording no repetition

layout: scattered, varied scale layered density (micro / mid / highlight)

realism: uneven spacing partial cutoff print + scan hybrid

rule: every line adds lore

=== 🔥 TAGLINE === short, dark, suggestive implies unseen world

=== 🔥 HARD RESTRICTIONS === NO extra colors NO colored lighting NO environment NO props NO messy UI NO filler text NO repetition
