Images captured with high-speed cameras may let you think that the famous s aying "seeing is believing" is not true in some cases. High-speed imaging of a droplet shows that the droplet behaves like a ball when it falls onto a piece of waterproof material. It will be compressed and bounces into the air after it drops and hits the material.

當(dāng)看見(jiàn)高速攝影所拍攝的圖像時(shí)，你或許會(huì)感覺(jué)到眼見(jiàn)未必為實(shí)。在高速攝影下，滴落到防水物料上的液滴像一個(gè)小球。接觸到防水物料后會(huì)壓縮，然后彈起。

To film this amazing phenomenon, a high-speed camera that can achieve extremely low exposure time, high frame rate and most importantly high sensitivity to capture the moment is required to show you the truth. For this application a pco.dimax camera was used.

在拍攝你現(xiàn)在所看見(jiàn)的畫(huà)面時(shí),需要通過(guò)打光凸顯液滴的形態(tài)。相機(jī)需使用極低的快門(mén)時(shí)間、極高的拍攝幀率進(jìn)行拍攝。但必須保證足夠的靈敏度，才可以拍攝到這個(gè)場(chǎng)景，揭示真正的物理狀態(tài)。
