我想問大家,v3快門速度可以有15sec........咁耐有什麼作用?因為我在好黑時用3-4sec已經很光,又冇得較光圈大小,請各位教教我~~thx!!

The manual shutter speed setting is not a shutter-priority auto mode. Therefore, the camera will not use a small aperture even such measure can prevent the photo from getting over-exposure.
Use a 8XND filter (hand held). Otherwise, over-exposure must occur.

據我所知,長快門是用來影星空等十分暗的地方,或用來做一些特別效果,如光線軌跡,無人的街道等.....
