In one mind map, Thomas lays out what time blending is, why modern commercial and landscape photography depends on it, and its five major applications: light blending, trail blending, sky-ground blending, motion-still blending, and noise reduction & clutter removal. All key points and keyframe screenshots are preserved here; read it first for the framework, then revisit the video for the details."},{"t":"p","x":"先复习定义。时间合成，就是让相机在三脚架上保持构图不变，在一段时间内——可能是几分钟、几小时甚至几天——连续拍摄多张照片，后期再合并到一个画面之中（视频 0:38 处）。它的核心思想是：每张照片不用管全局，只需保证画面中某一个局部达到最佳状态，最后把所有「局部最佳」合并起来，就得到一张每个角落都无可挑剔的照片。相比单张出片，成功率天差地别。","xe":"First, the definition. Time blending means locking the camera on a tripod, shooting many frames over a stretch of time — minutes, hours, even days — and merging them into one image in post (at 0:38 in the video). The core idea: each frame only needs one region of the frame at its best; merge every 'local best' and you get a photo where nothing is compromised — a success rate no single frame can match."},{"t":"img","f":"v01","w":852,"h":480},{"t":"p","x":"按应用情境，Thomas 把时间合成分为五大类：光线合成、轨迹合成、天地合成、动静合成，以及降噪与去杂物。下面的展开与这棵导图一一对应（视频 2:17 处）。","xe":"By scenario, Thomas splits time blending into five categories: light blending, trail blending, sky-ground blending, motion-still blending, and noise reduction & clutter removal.

Shooting a car outdoors: you have few lights, and firing them all at once causes interference. The fix is one light per frame — first the front, then the side, then a dedicated pass on the wheels for texture — and merge.

Because at sunset the lamps are off, and by the time they light up the sky is black. Keep the tripod put: shoot the sky at sunset, shoot again after the lights come on, and blend the lights into the dusk base with the Lighten mode.
