小弟是初哥, 剛買了 P200, 佢有個 M mode, 可手調快門曝光時間, 但可調數直係由1000, 800, 640, 500,400,320, 250,200,160,125,100,60,50,40,30,25,20,15,.....nr6,nr5,.....nr1.5, nr1.3....nr1",nr1.3".......nr30", 等, 咁點睇代表幾多秒架??
好似想影夜景(由尖咀影番去HK或D車頭燈光流)咁, 應 set 幾多秒好D呢?
多謝指教

1000, 800, 640......nr1.3=1000/1 sec, 800/1 sec, 640/1 sec....1/3 sec. nr1"....nr30"=1 sec....30 sec.
