桃红背景，只留一条侧脸线
光圈开到最大，只留轮廓那条边，色不脏，也不糊
✍️ 轮廓类的片子最怕背景发闷，这条靠大光圈虚化和低ISO两头夹——光圈管边缘干不干净，ISO管桃红色纯不纯，两个都到位剪影才立得住。
📋 提示词 Midjourney 参数式
A woman's profile is reduced to pure silhouette, her edge the only thing the lens cares about. The backdrop is a saturated hot pink pushed to its most vibrant register, and the setup mimics a wide-open aperture so everything but that contour falls away into contrast. ISO stays low to keep the color dense and grain-free, rendered photorealistic at UHD resolution. --ar 9:16 --chaos 1.7 --style raw
📋 中文译写版 Midjourney 参数式
一位女性的侧脸只剩下纯粹的轮廓，镜头只关心那条边缘线。背景是推到最饱和的桃红色，模拟大光圈拍法让轮廓以外的一切都退进强对比里。ISO压得很低，色彩浓郁不出颗粒，成片走photorealistic路线，UHD分辨率。--ar 9:16 --chaos 1.7 --style raw
