Showing the whole of a person, from head to feet, with nothing cut off. It is used about mirrors, photographs, portraits and other pictures.
全身的
核心畫面
Picture something measured from one end to the other, with nothing trimmed off either end. The thing being measured is usually a person. A full-length mirror gives you your shoes as well as your face; a full-length dress runs the same distance in cloth; a person lying full-length takes up every they have. When the thing being measured is a film or an album instead of a body, the idea does not change: you are getting the whole of it, not a short version.

可以想成一件東西從這一端量到另一端，兩頭都沒有被切掉。被量的通常是一個人。a full-length mirror 照得到臉，也照得到鞋子；a full-length dress 用布走完同樣這段距離；一個人 lying full-length，就是把自己的每一公分都攤開來。被量的換成電影或專輯時，想法還是一樣：你拿到的是完整的那一個，不是剪短的版本。From the word’s history
The word is simply full plus length: the whole of the length, not a part of it. That literal make-up is still exactly what every use of the word does.
這個字就是 full（滿的、完整的）加上 length（長度）拼起來的：整個長度都在，不是其中一段。這個字面組合到今天仍然說明了它所有的用法。
