昆虫摄影：慢下来才能看到的世界ForveteranwildlifecameramanKevinFlaytheinsectworldisthe“mostincrediblething〞andhisuseofslowmotionphotographytocaptureitsintricaciesmakeseveryshotarevelation.在经验丰富的野生动物摄影师凯文·弗莱眼中，昆虫的世界是“最令人惊叹的〞，他用慢镜头捕捉其中的纷繁复杂，每个镜头都出人意料。Normallythehumaneyewouldwatchafilmat25framespersecond，butspeciallyadaptedcamerasnowallowustofilmat500framesasecond—theperfectspeedtocaptureafrogjumping，forexample.通常人们所看的电影速度是每秒25帧。现在，我们可以利用特制相机以每秒500帧的速度进行拍摄，非常适合捕捉青蛙跳跃等瞬间。Nowthatmightsoundfast，butfilmingtherapidmovementofinsectsrequiresawholenewleveloffast.Flaywantedtocaptureoneparticularbugthatthrewitselffromoneplanttoanother.Evenat500framesasecondhecouldnotcapturethisinsect，movingfasterthanabulletfromagun，soheacquiredacamerathatshot10，000framesasecond.Thisallowedhimtoseethatthistinybuglockeditslegjointstogiveittheleveragetomakeitsenormousleaps.Theresnowayhecouldhavecapturedthiswithoutdigitalslow-motion，andwedneverhaveknownhowtheinsectmoved.這个速度听起来可能很快，但拍摄昆虫的快速移动对速度的要求完全是另一个级别。弗莱想要拍摄一只虫子从一株植物跳到另一株上，但即使在每秒500帧的速度下，他仍然无法捕捉到这个过程，虫子跳得比射出枪膛的子弹还快。所以他购置了一部每秒速度高达1万帧的相机，能看到小虫子收紧了腿关节，以此为支点完成了如此远距离的跳跃。如果没有数字慢镜头，他永远也拍不到这个画面，我们也永远无法了解这种昆虫是如何移动的。Theuseofdigitalfilmhasremovedmuchoftheelementofchancefromslow-motionphotography，andsavedagreatdealofwaste.Usingfilmmeantpressingabuttonandhopingandthesheernumberofframesusedmeantthefilmwouldonlylastacoupleofminutesbeforerunningout.Atnormalspeed，thefilmwouldlastnineminutes，butwhenFlayshotinhisslow-motioncameraheduse30secondsoffilm.Ifnothinghappenedinthat30secondsthenthefilmwasdestinedforthebin.Theleveloflightingrequiredalsomadeshootsincrediblyhotanduncomfortable—Flayrecallshavingtowearweldinggogglestoshootfleasjumping.数字摄像...
