扭曲的快速世界:有趣的「Rolling Shutter」效應相片

看到下面的相片,你一定難以相信自己的眼睛:用相機拍攝快速移動的物體,如飛機螺旋槳、車外的景物、疾駛的火車、揮舞的高爾夫球桿等,竟然都出現了有趣的扭曲現象。

事實上,只要你的相機是使用 CMOS 感光元件,由於其傳輸影像資料的特性,在拍攝快速動作的物體時,經常容易出現這樣的現象,稱為「Rolling Shutter 效應」。

有時它會造成令人困惑的影像扭曲,有時它卻能創造出極富創意的視覺經驗;現在多數手機和數位相機都使用 CMOS 做為感光元件,所以很可能也能拍出這樣的相片,各位不妨也試試看吧!

THE PLIGHT OF THE HONEYBEE

Aristotle had a beautiful mind. And a hunch about honeybees. He thought they collected honey from rainbows. He may not have gotten the science right but he sensed that there was more to bees then their bristling good looks. 336 more words
