Thomas's recent photo from Laigu Glacier in Tibet shows an emerald, translucent iceberg under the Milky Way — yet the only light painting that 10-meter ice was an ordinary headlamp. The full workflow is laid out below with keyframe screenshots: why the ice needs light, how time blending builds a 360-degree lighting rig, how a dozen-plus frames merge layer by layer, and how the sky is processed and star-reduced.","b":false},{"t":"p","x":"先看总览。下面就是最终成片：被头灯多角度点亮的冰山通体透亮，两位摄影师的工作状态留在画面中，头顶是赤道仪与天文改机拍下的银河。整期教程，就是把这张照片从黑暗里一层层「合」出来。","xe":"Start with the overview — the final image: an iceberg lit from multiple angles by a headlamp, two photographers' working poses left in the frame, and the Milky Way captured with an equatorial mount and an astro-modified camera overhead.

The reason is direct — the same iceberg, unlit, shows only a faint sheen; but with the sun behind or beside it, its color, texture and layering change completely. To express the ice's structure, light is everything (at 0:23 in the video).","b":false},{"t":"img","f":"v02","w":768,"h":480},{"t":"img","f":"v03","w":768,"h":480},{"t":"p","x":"一个反面教材：Thomas 借了朋友的天文改机专门拍星空，但那张照片里冰川没有任何光线——冰山上泥土发脏、显得呆板，完全没有冰的透亮层次（视频 1:02 处）。当时他就想打光，可头灯功率再强，和七八米高的冰山比也太小了，所以必须前后期配合，用时间合成的方式给冰山打光。","xe":"A cautionary example: using a borrowed astro-modified camera, Thomas shot the sky alone — but with no light on the iceberg, the dirty, dull ice shows none of its translucent depth (at 1:02 in the video). He wanted to light it then and there, but even a strong headlamp is tiny next to a 7-8 meter berg; the solution is to combine fieldwork and post, lighting the ice through time blending.","b":false},{"t":"img","f":"v04","w":768,"h":480},{"t":"h","x":"02 一盏头灯的 360 度布光","xe":"02 A 360-Degree Lighting Rig with One Headlamp"},{"t":"p","x":"前期布光从轮廓光开始：把头灯绕到冰山后面，被照亮的冰立刻有了亮部与暗部、均匀的过渡和显现出来的纹理，层次感十足（视频 1:42 处）。把光打得更猛、偏向一侧，有光与没光两侧的细节表现堪称天壤之别——有光时冰的色彩、纹理、层次、细节全部出来，没光时看上去就像一个土坡（视频 1:57 处）。","xe":"Field lighting starts with a rim light: wrap the headlamp behind the berg, and the lit ice instantly gains highlights and shadows, even transitions and visible texture (at 1:42 in the video). Swing the lamp harder to one side and the difference between lit and unlit halves is day and night — color, texture, layering and detail all emerge where light falls; without light, the ice looks like a dirt mound (at 1:57 in the video).","b":false},{"t":"img","f":"v05","w":768,"h":480},{"t":"img","f":"v06","w":768,"h":480},{"t":"p","x":"接下来就是不断地改变光线：这一束取冰山左上角的形态，中间那束把两块冰的层次、纹理和颜色照出来（视频 2:20 处）。两位队友后来也走到冰中互相拍摄，Thomas 觉得这个场景很有意思——它表现了风光摄影师真实的工作环境与状态，于是决定把人物也拍进最终成片（视频 2:36 处）。","xe":"From there, keep changing the light: one pass grabs the upper-left form of the berg, another brings out the layering, texture and color of the two central ice blocks (at 2:20 in the video). His two teammates later walked among the ice, photographing each other — a scene Thomas found compelling, showing the landscape photographer's real working environment, so he decided to include the figures in the final frame (at 2:36 in the video).","b":false},{"t":"img","f":"v07","w":768,"h":480},{"t":"img","f":"v08","w":768,"h":480},{"t":"h","x":"03 后期合成：变亮组、蒙版与十几张底片","xe":"03 Blending in Post: Lighten Groups, Masks and a Dozen-Plus Frames"},{"t":"p","x":"打开 PSD，底板是抓拍的人物：一张 3 秒的短曝光定格（视频 3:02 处）。其余冰川的光线图层，一个个慢慢融合进来——先把它们放进一个组，组的混合模式设为「变亮」：只会把比当前图层更亮的部分融合进来，更暗的部分自动忽略。再配合蒙版，控制每个图层只显露需要的那一部分，比如某个光源只取它照亮最好看的那块冰（视频 3:23 处）。","xe":"Inside the PSD, the base is the candid figure — a 3-second exposure freezing the pose (at 3:02 in the video). The glacier's lighting layers merge in one by one: first grouped, with the group's blend mode set to Lighten — only pixels brighter than the layers below come through, darker ones ignored automatically.

Local refinement follows: lift a region with Curves before blending it in, and where the lit ice lacks bounce light, cover it with a fresh layer (at 4:00 in the video). In the field Thomas circled the berg with his headlamp for over ten minutes, collecting light from every direction; in post he keeps each direction's best-lit patch and merges them into one perfectly lit iceberg (at 4:26 in the video).","b":false},{"t":"img","f":"v11","w":768,"h":480},{"t":"p","x":"合成里还有几个关键层：先给前景加一个基础光——后面打得那么亮、前景又黑，反差太猛；左上角高光也补一笔。最核心的一张，中间很亮、着重把两侧冰的颜色和质感打出来，再用亮度蒙版把中间高亮部分隐掉，形成渐进的结构（视频 5:01 处）。地面部分则取队友把手电筒放在地上打出的那个光线角度，替换掉杂乱的光斑；最后把人物稍稍提亮，冰川就有了比较完美的效果（视频 5:51 处）。","xe":"A few more key layers: a base light for the foreground first — otherwise the bright berg against a black foreground is far too harsh — plus a highlight pass on the upper left. The most crucial frame lights the center brightly and brings out both sides' color and texture, then a luminosity mask hides the center highlights into a gradual structure (at 5:01 in the video). For the ground, he borrows the angle from a teammate's flashlight laid on the ice, replacing the messy pools of light; a slight lift on the figures, and the glacier reaches its near-perfect state (at 5:51 in the video).","b":false},{"t":"h","x":"04 星空：赤道仪、改机与缩星","xe":"04 The Sky: Equatorial Mount, Modified Camera and Star Reduction"},{"t":"p","x":"冰川合并完成后先 Topaz 降噪，然后才处理星空：用蒙版快速把星空部分抠出来，换上单独拍摄的星空底片——那是在赤道仪上用改机拍的，星云已经隐隐约约显现（视频 6:52 处）。这张复杂照片的底片有十几张，每一张只负责画面的某一小部分。","xe":"Once the glacier is merged, run Topaz Denoise before turning to the sky: mask the sky out quickly and swap in the separately shot sky plate — taken on an equatorial mount with the modified camera, where faint nebulae already show (at 6:52 in the video).

The figures' white jackets, dull and blending into the ice, get painted with color — orange proves too loud, so Hue/Saturation shifts it to a deep, saturated cyan that separates from the background without shouting (at 7:52 in the video).
