You should use the fill-in flash.
Ian: I'm a bit disappointed with some of my vacation snaps.
Bob: They mostly look fine to me.
Ian: But on these where I photographed my friends against the sun, their
faces are quite dark. You can't really see them clearly.
Bob: Ah, in those kind of conditions you should use the fill-in flash setting on your camera.
Ian: What will that do?
Bob: It will make their faces lighter so that you can see them better when the sun's behind them.
奕恩：我對(duì)假期拍的一些生活照不太滿(mǎn)意。
巴布：我看大部分都不錯(cuò)啊。
奕恩：但請(qǐng)看這幾張，我拍時(shí)，朋友背向著太陽(yáng)，結(jié)果面孔頗為陰暗，實(shí)在看不清楚。
巴布：啊，在這樣的情況下，你應(yīng)該用照相機(jī)的補(bǔ)充閃光裝置。
奕恩：這有什么用處？
巴布：閃光裝置會(huì)使面孔看起來(lái)光亮一點(diǎn)，這樣，太陽(yáng)在你的朋友背后，他們的樣子也會(huì)清楚些。
太陽(yáng)下拍照往往不容易：面向陽(yáng)光，眼睛會(huì)不由自主瞇起來(lái)；背向陽(yáng)光，面孔光線不足；正午太陽(yáng)當(dāng)頭，則眼眶和鼻子、嘴巴的陰影很不美觀。用一般閃光燈（flash），可以憑其強(qiáng)光清除陰影，但照片看來(lái)會(huì)不自然，所以用較柔和的補(bǔ)充閃光（fill-in flash）: If you don't want your subject（拍攝對(duì)象）to squint（瞇著眼睛）in the sun, or to have dark eye sockets（眼窩）and shadows under the nose and lips, you may shoot（拍攝）him against the sun using fill-in flash.
Flash除了指'閃光燈'，還可解作'閃光'.有些人不用補(bǔ)充閃光燈，而用反光板，那英文叫做reflector，例如：As more light was needed on her face, we sent for a reflector（她臉部要多點(diǎn)光，我們于是叫人拿塊反光板來(lái)）。奕恩拍照沒(méi)有用補(bǔ)充閃光燈或反光板，拍出來(lái)的照片就不稱(chēng)心：I'm a bit disappointed with some of my vacation snaps.Snap作動(dòng)詞，本來(lái)是'迅速抓住'的意思，例如：I snapped at the chance of working with such a brilliant scientist（有機(jī)會(huì)和這樣出色的科學(xué)家合作，我當(dāng)然不會(huì)放過(guò)）。用照相機(jī)，可以抓住事物一時(shí)的神態(tài)，所以snap常引申解作'拍照'，例如：I snapped my son while he was happily eating ice cream（我趁兒子快快活活吃冰淇淋的時(shí)候，幫他拍了照片）。作名詞，snap或snapshot即'快照'、'便照'，例如：I took a snap of the volcanic eruption（我拍了火山爆發(fā)的照片）。
