Deleting tourists from your travel photos
從旅行照片中刪掉遊客
Put your camera on a tripod
照相機放三腳架上
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-統計”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”時只有15張照片像素相同那些不屬於移動物體（遊客）的才能被覆蓋。
People agree that it works both in theory and practice.
人們認爲這在理論上和實際上都行得通。
Obviously more number of images will improve the quality of output.
很明顯照片越多最後出來的效果越好。
