Chings,

Last night just saw the advertisement of Blue Girl, they set up the camera system trap for the birds in forest.......

Any idea of how that could be set up?

以前上攝影班玩過，係類似laser pointer的東西，如有物件阻擋到laser光柱，就會trigger快門。 嗰陣主要係用來影高速物件，如飛標飛向一個裝滿水的氣球，氣球剛剛爆的一瞬間，人手按快門就極難中。

好多森林野生動物的記錄片都有用呢個技術，因為一d動物帶有攻擊性唔可以行得太近去影，或者稀少得你唔知幾時先會遇到佢就擺部機同紅外線sensor去守株待兔
