请教大牛们:
我刚搞了一只Sekonic 308。在我测试闪光测光模式的时候,发现只有把快门速度设在
60的时候测出来读数是对的,比如我meter的快门速度设成125,给出的光圈导致照片严
重过曝,如果是设成30,就会低曝。这个正常么?难道侧闪光一定要与闪光的长度同速
么?

Ok, I did some research on that and it seems I am not the only person who
ever got this problem.
Some ppl said it could be because some pre-flash and/or some metering light
from the flash or ther camera baby triggered the meter to read before
the major flash launched, so the meter gives a wide opern aperture reading.
As for why 1/60 sec setting get better readying, my guess is that the
interval between pre-flash is some where between 1/60 sec and 1/125 sec, so
when the meter is set at 1/60 or ev

你都测光表了
闪光灯肯定是M档
为啥还会有preflash?
light
.
so
, but the best way to do it would be to triger the meter with a sync cord as
appose to set it in the auto wireless mode.

good question, that is exactly something I need to figure out....I pressed the pilot button on the flash and I believe that should give the same amount of light as in M mode 1/1, and the meter gave right reading, so I guess the meter is not borken... there must be something wrong with the setting

问题解决了。我想毛病出在之前我把580II设成wireless 模式,来slave别的灯,不知
道怎么那样的话快门速度高于1/60秒就无法测准。现在我把580II设成唯一的灯,这样
的在高速快门下meter给出的光圈读数也是对的。至于究竟是为什么会有这样的区别,
我现在也没有搞明白。不过至少知道meter是好的,设置的问题以后可以慢慢研究
了. 附小猪照一张
