中文提示词
选取参考图像中的人物,创建一个 2x2 的网格,展示同一张特写肖像在四种不同专业灯光设置下的效果。身份锁定:每个面板中的面部、表情(冷静中性)、发型、深色上衣、头部大小和拍摄角度必须完全一致,仅改变灯光。面板 1 伦勃朗光 (REMBRANDT):主光位于左上方 45 度,阴影侧脸颊呈现小三角形光斑,光影过渡富有质感。面板 2 蝴蝶光 (BUTTERFLY):主光位于相机正上方,鼻下形成柔和对称的阴影,呈现美妆肖像光泽。面板 3 侧光 (SPLIT):主光完全从侧面照射,半边脸受光,另半边处于黑暗中。面板 4 轮廓光 (RIM):主光位于主体后方,勾勒出头发和肩膀的明亮轮廓,面部仅由微弱的补光提亮,营造近乎剪影的戏剧感。全程使用相同的 {argument name="background color" default="medium-gray"} 背景,85mm 镜头感,焦点清晰对准眼睛。每个面板下方标注白色小标签:“REMBRANDT”、“BUTTERFLY”、“SPLIT”、“RIM”。
原始提示词
Take the person from the reference image and create a single 2x2 grid showing this exact same close-up portrait under four different professional lighting setups. Identity lock: identical face, expression (calm neutral), hairstyle, dark top, head size and camera angle in every panel — only the light changes. Panel 1 REMBRANDT: key at forty-five degrees left and above, small triangle of light on the shadowed cheek, moody falloff. Panel 2 BUTTERFLY: key directly above the camera, soft symmetric shadow under the nose, beauty-portrait glow. Panel 3 SPLIT: key exactly from the side, one half of the face lit, the other in darkness. Panel 4 RIM: key behind the subject edging hair and shoulders in bright outline, face lifted only by faint fill, near-silhouette drama. Same {argument name="background color" default="medium-gray"} background throughout, 85mm look, sharp focus on the eyes. Small white labels beneath each panel: "REMBRANDT", "BUTTERFLY", "SPLIT", "RIM".
