Thanks stlam! I will try it next time. I hope can do it. :-)

Just for sharing... If the light contrast is high, and the light source is stable not moving object. You can increase the shuttle time. Let say if you think it need 2 s for the bright duck, and it need 5 s for the dark background. Try to set the exposure to 5 s, count 2 s and then use a black card (non-reflecting one) to cover the bright object for 3 s. It will get a less contrast photo.

想請教各方高手，我覺得在這些地方影相十分困難，如這一張，周圍環境十分黑，只有「鴨光」，我就覺得影出來的都十分黑，我試過很多光圈和快門的組合，但都係不理想，如果快門慢Ｄ，Ｄ鴨仔就爆光，但係快門快Ｄ又會好黑，老實說光圈的控制還是不太好，於是在無法可想時，現在的這幅的影法是，不理周圍，只著重鴨仔的暴光，所以出了這張相，鴨仔就ＯＫ，但周圍就……，請問有冇高手可以指教指教呢？

fun..........

鴨...鴨...! very funny~ vote
