※ 引述《momokoshi ()》之銘言： : 感謝板主的推文，讓我恍然大悟啊 : 昨天半夜用家裡的小閃燈作了測試，證實是觸發模式的問題 : 設定在X模式之後就能正確曝光了 : 家裡有類似TLR的人可以參考一下 (還是只有我這麼笨 @~@) 請參考 photo.net 上面的這一篇 http://photo.net/bboard/q-and-a-fetch-msg?msg_id=009es7&tag= 摘錄如下： ""X-sync" is the flash synchronization setting to be used with electronic flash units (nowadays that means all flash units). There are/were different synchronization settings because different types of flash (bulbs) took different amounts of time between start of ignition and the moment they burned (literaly) brightest. Electronic flash units reach full power output instantly(as good as)." "In the old days, there were three types of flash synchronization: x (instantaneous), f (5 milliseconds) and m (20 milliseconds). F and M sync were used for flash bulbs. The bulb was fired before the shutter was fully open to allow for the delay reaching full intensity: 5 ms for gas bulbs (clear with a single, short filament) and 20 ms for wire-filled bulbs. At X-sync, the flash is fired at the instant the shutter is fully opened." : : -- : 推 Mithrandir:應該要設定在X，我覺得現在的棚燈原理應該也算是 12/19 19:27 : → Mithrandir:電子觸發了 12/19 19:28 X stands for Xenon 現在的棚燈多是大管的 xenon tube : 推 HITACHI:看你要不要用PC點觸發小閃燈來試拍個幾張 要的話我帶線 12/19 19:44 : 推 momokoshi:板大一語驚醒夢中人，家有一顆古董小閃燈用同步線的 XD 12/19 21:41 : → origin2:感覺上應該是閃光燈出力設定有問題. 有先用測光表測過閃燈 12/19 22:22 : → origin2:出力嗎？ 12/19 22:23 : : 呃.. 用棚燈不可能不測光吧 ~"~ :p 其實大多數的問題上 photo.net 翻可以直接找到答案 --
