Deleting tourists from your travel photos
從旅行照片中刪掉游客

Put your camera on a tripod
照相機(jī)放三腳架上

Take about 15 pictures about every 10 seconds
每10秒拍15張照片

Open them all in Photoshop from File->Scripts->Statistics. Choose "median".
在Photoshop中從“文件-腳本-統(tǒng)計(jì)”中打開所有照片，選“中間值”。

Layman's Logic: Only constant pixels in all 15 images are those, that don't belong to the moving objects(tourists) and get cancelled out while taking median.
外行人的邏輯：取“中間值”時(shí)只有15張照片像素相同那些不屬于移動(dòng)物體（游客）的才能被覆蓋。

People agree that it works both in theory and practice.
人們認(rèn)為這在理論上和實(shí)際上都行得通。

Obviously more number of images will improve the quality of output.
很明顯照片越多最后出來的效果越好。
