职业病，平时修片盯眼神光盯多了，就想看看极端微距下一只眼睛能撑起多少信息量。跑了十来版，前面几张要么虹膜纹理糊成渐变、要么瞳孔里被硬塞一坨假高光，看着就是塑料球。后来把光源写死成一条冷调 LED 条形柔光箱、只留一道细月牙反光，质感立刻从假变真——反光形状比反光强度重要得多。
完整版提示词：
An extreme macro close-up photograph of the eye of a Great Horned Owl, 100mm macro lens, 1:1 magnification.
A single mammoth tubular eye fills the entire frame, edge to edge.
The vitreous deep-amber iris reveals microscopic radiating fibrous lattice textures, fine striations shifting from honey-gold near the pupil to burnt amber at the rim.
The central pupil is an absolute, light-absorbing carbon-black circle, perfect mathematical circularity, razor-sharp edge, no internal highlight.
The glassy cornea acts as a flawless high-refractive-index lens, catching one sharp, razor-thin crescent reflection of a distant cold LED strip softbox at the upper left.
Feather barbs and eyelid skin texture stay in focus at the frame edge.
Neutral cool white balance, high micro-contrast, hyper-realistic, 8K resolution, zero-tolerance anatomical definition, no sharpening halos.
那句 no internal highlight 是后加的，加之前基本每张瞳孔里都有多余的亮点。
