自從實驗室買了新武器後（Phantom的高速攝影機）
就一直很想拿來拍我家的塞內加爾（畢竟青春不留白呀！）
一年多前曾用舊型的高速攝影機拍我家泡芙
但那台最高只有每秒1000張，且是黑白畫面
現在有了每秒上萬張的高速攝影機，還是彩色的！
當然要拿來拍一下泡芙囉（順便熟悉新器材）
畫面解析度為：1280*800 (因為泡芙翼展大，故要選擇大的畫面解析度）
Frame rate = 2000 Hz (每秒2000張)
之所以只使用每秒2000張，是因為今天主要是和負責實驗設備的學弟學習使用新攝影機
加上是拍寵物，所以實驗架設很簡單（只隨便拿了一盞冷光燈補燈）
這樣子直接調整攝影機CCD的曝光時間就可以了，但若將曝光時間變長
相對的Frame rate就會變小，所以就先用每秒2000張試拍一下囉！
以後有空再用每秒上萬張拍泡芙 ^^"
光圈是1.2，所以景深不算大，泡芙很容易飛出焦距外
成果如下：
Puff: My Senegal Parrot (under the high speed camera) Part 1
http://www.youtube.com/watch?v=mOa0wcJ4nsc
拍攝時每秒兩千張，播放時使用10fps(每秒十張)
Puff: My Senegal Parrot (under the high speed camera) Part 2
http://www.youtube.com/watch?v=0FjfzoWisGg
拍攝時每秒兩千張，播放時使用20fps(每秒二十張)
Puff: My Senegal Parrot (under the high speed camera) Paryt 3
http://www.youtube.com/watch?v=IdK8ehLVsj8
拍攝時每秒兩千張，播放時使用30fps(每秒三十張)
影片裡的肥手就是我
第三個影片是泡芙往我身上飛
但因該影片中我的臉入鏡了，目前是用很粗糙的方是把我的頭剪掉
所以畫質會比前兩個差一些
