提示词内容

中文提示词

目标:创建一张并排对比图,展示同一张动漫插画在应用全局光照 / 间接反射光后的改进效果。

画布:宽屏 16:9 横向图像,精确平分为左右两个垂直面板,中间有一条细白色分割线。采用柔和的淡彩动漫插画风格,营造梦幻般的晨光氛围。

布局:左侧面板左上角标注“Before”(对比前),展示普通版本;右侧面板右上角标注“After”(对比后),展示增强版本,需包含更温暖的间接光、自然的接触阴影以及环绕主体的柔和光晕。在顶部居中添加大标题 {argument name="headline text" default="プロンプト比較:光の回り込みGI"}。在左侧面板左下角添加日语标签 {argument name="left bottom label" default="通常生成"},在右侧面板右下角添加日语标签 {argument name="right bottom label" default="光の回り込みGI"}。所有叠加文字均为加粗白色,并带有深色投影以确保可读性。

主体细节:两个面板中均展示同一位中性风动漫少年,坐在室内明亮的窗边。他拥有蓬松的层叠式 {argument name="hair color" default="银白色"} 头发,带有淡紫色阴影,皮肤白皙,身材修长优雅。他的面部在每个面板中均被一个居中的大号不透明淡紫色方形遮挡块刻意遮盖;总共使用 2 个遮挡块,每个面板一个。他的右手靠近脸颊,在遮挡块旁部分可见。他身穿奢华的白色长袍或类似和服的上衣,内衬为深蓝色,袖口宽大,边缘饰有金属银边,并装饰有星星和新月图案。佩戴一条带有蓝色宝石吊坠的新月项链。

背景细节:房间内包含 1 扇位于主体后方的落地窗、柔软的窗帘、一张床或软垫座椅、一个摆放着香水瓶和装饰品的小架子或窗台,且每个面板中均有 1 个悬挂的新月装饰。色调为淡紫色、白色、淡蓝色和温暖的阳光。

光照对比:左侧“Before”面板应看起来更平淡、更冷,反射光较少,阴影较弱。右侧“After”面板应明显提升深度:增加柔和的全局光照,温暖的阳光环绕头发、面部区域、手部、长袍褶皱和肩部;在手部接触面部区域以及袖子重叠处增加细微的接触阴影;在窗户附近增加光晕效果,并在头发上增加更明亮的轮廓光。保持两个面板中角色的姿势和构图完全一致。

约束条件:可数元素必须保持精确:2 个对比面板、1 条垂直分割线、总共 4 个文字标签、2 个面部遮挡块以及 2 个悬挂的新月装饰。无水印,无额外 Logo,无额外面板。

英文提示词

Goal: Create a side-by-side comparison graphic demonstrating global illumination / indirect bounce lighting improvement on the same anime illustration.

Canvas: Wide 16:9 horizontal image, split exactly into two equal vertical panels with a thin white divider line down the center. Use a soft pastel anime illustration style with dreamy morning light.

Layout: The left panel is labeled “Before” at the top-left and shows the normal version; the right panel is labeled “After” at the top-right and shows the enhanced version with warmer indirect light, natural contact shadows, and soft glow wrapping around the subject. Add a large centered headline across the top reading {argument name="headline text" default="プロンプト比較:光の回り込みGI"}. Add bottom-left Japanese label {argument name="left bottom label" default="通常生成"} on the left panel and bottom-right Japanese label {argument name="right bottom label" default="光の回り込みGI"} on the right panel. All overlay text is bold white with a dark drop shadow for readability.

Subject details: Show the same androgynous anime boy in both panels, seated indoors in a cozy bedroom by a bright window. He has fluffy layered {argument name="hair color" default="white-silver"} hair with lavender shadows, pale skin, and a slim elegant build. His face is intentionally covered by one large opaque pale mauve square censor block centered over the face in each panel; use exactly 2 censor blocks total, one per panel. His right hand rests near his cheek, partially visible beside the censor block. He wears a luxurious white robe or kimono-like top with navy-blue inner layers and wide sleeves, trimmed with metallic silver edges, decorated with star and crescent moon motifs. Include a crescent moon pendant necklace with a dangling blue gemstone.

Background details: The room contains exactly 1 large window visible behind the subject, soft curtains, a bed or cushioned seat, a small shelf or windowsill with perfume bottles and ornaments, and exactly 1 hanging crescent-moon decoration on each panel. The palette is lavender, white, pale blue, and warm sunlight.

Lighting comparison: Left “Before” panel should look flatter and cooler, with less bounce light and weaker shadows. Right “After” panel should visibly improve depth: add soft global illumination, warm sunlight wrapping around hair, face area, hands, robe folds, and shoulders; add subtle contact shadows where the hand touches the face area and where sleeves overlap; add bloom near the window and brighter rim light on the hair. Keep the character pose and composition identical between panels.

Constraints: Countable elements must remain exact: 2 comparison panels, 1 vertical divider, 4 text labels total, 2 face censor blocks, and 2 hanging crescent decorations. No watermark, no extra logos, no additional panels.
