The finished frame above, captured at 10:54 in the video, shows Charles Bridge at dawn, empty except for the statues, the cobbles and the morning light — while the scene itself was bustling with people.

Lock the camera on a tripod so the framing never shifts, then switch on the interval timer — say one frame every 10 seconds; or fire manually every 10 to 15 seconds (at 0:54 in the video)."},{"t":"img","f":"v01","w":852,"h":480},{"t":"p","x":"视频 1:01 处展示了相机菜单里的实际设置：间隔拍摄功能开启，拍摄间隔 10 秒一张，张数直接拉满。这样的一个构图连续拍 3 到 5 分钟，后期就有足够的素材可以把人物尽量去除（视频 1:06 处）。","xe":"At 1:01 in the video we see the actual camera menu: the interval timer enabled, one frame every 10 seconds, the shot count maxed out. Keep shooting the same composition for 3 to 5 minutes and you will have plenty of material to erase people later (at 1:06 in the video)."},{"t":"img","f":"v02","w":852,"h":480},{"t":"p","x":"之所以行得通，是因为绝大多数游客一直在移动：这一张他站在画面左边，上一张那里却是干净的背景；红衣服的人挡住的位置，多拍几组后总有他走开、别人又没补上的一瞬（视频 1:29 处）。Thomas 在同一机位拍了 60 多张，最后挑出 30 多张参与运算（视频 2:04 处）。","xe":"This works because most tourists keep moving: in one frame he stands on the left of the frame, in the previous one that spot is clean background; wherever the person in red is blocking, a longer burst will always catch the moment he walks away and nobody else has stepped in (at 1:29 in the video).

Then run Layer → Smart Objects → Stack Mode and choose Median (at 3:37 in the video): if only four or five frames have a person in a given spot and the other 30 are clean, the median picks the clean one — the more a tourist moves, the more completely they vanish."},{"t":"img","f":"v05","w":852,"h":480},{"t":"p","x":"一次简单的中间值运算之后，画面已经非常干净，但仍有瑕疵（视频 4:13 处）：一直没被移走的背包、出现次数超过一半的三脚架、以及某个区域 20 多张里始终有人——哪怕不是同一个人——算出来就是一团黑色人影。中间值能快速去除运动幅度大的前景游客，这些顽固残留则要交给下一步（视频 4:24 处）。","xe":"After one simple median pass the frame is already very clean, but flaws remain (at 4:13 in the video): a backpack nobody ever picked up, a tripod present in more than half the frames, and a spot occupied in 20-plus frames — even by different people — that blends into a dark ghost.

The layers thus cover for each other — take from every layer only the part with nobody in it, and the mid-ground ghosts and tourists are replaced one by one.

Two options here: the first is to accept them. Pick the source frame with the cleanest background and paint the distant tourists and lamps back in with the white brush, so all figures dissolve into the far distance — with the foreground and midground completely clean, the image already reads beautifully (at 9:55 in the video)."},{"t":"img","f":"v11","w":852,"h":480},{"t":"p","x":"第二是用仿制图章和选区画笔对远处的人慢慢涂抹，重新把远景画出来，得到连远景游客都没有的照片（视频 10:54 处）。对大多数人来说，做到「只有远景偶尔有人」的程度就已经非常干净了。视频 11:15 处的最终对比：处理前是逛来逛去的人、飞来飞去的鸽子；处理后，中间值堆栈去掉近景，蒙版换掉中景，仿制图章清完远景。","xe":"The second option is the Clone Stamp tool and selection brushes, dabbing at the distant figures and repainting the far background for a photo with no background tourists at all (at 10:54 in the video). For most people, reaching \"the odd distant visitor only\" is already remarkably clean.

Shooting sets the ceiling: lock the composition on a tripod, fire an interval of about 10 seconds for 3-5 minutes — the more frames, the easier the cleanup; 2.
