查询词典 underexpose

Some cameras have a quite limited compensation range; for example, the Canon 350D allows to underexpose or overexpose just up to 2 stops.

一些相机对曝光补偿的范围是有限定的，例如佳能的350d相机只能补偿两档。

Most point-and-shoot cameras have a simple exposure override facility, normally allowing you to overexpose or underexpose your picture. So if the subject is predominantly dark, experiment by overexposing to compensate. If the subject is predominantly light, then underexposure is the way to go. Try taking a test picture, look at it on the screen on the back of your camera, check the histogram, and adjust your exposure compensation. Don't be afraid to shoot four or five versions, as the LCD screen is not always accurate. You can delete the bad pictures later.

大多自动数码相机都具有曝光优先功能，一般都允许你在拍照时过度曝光或曝光不足，如果被拍摄物体整体光线比较强，可以减弱曝光强度，如果被拍摄物体整体光线比较弱，可以选择过度曝光，试着多拍摄几张照片，通过相机背部的液晶屏观察柱状图，调节曝光补偿等级，因为液晶屏的显示效果不很精确，别嫌麻烦，多拍几张照片，之后，对于效果不理想的照片可以删除。

Take care when metering water as the large areas of white can fool the meter to underexpose, making the picture look dark.

注意计时器，当水面有一大片白色区域时，会让计时器曝光过度，让照片看起来发暗。

And, since the camera has kept the overall ISO to 200, there isn't the same noise penalty to be paid as when conventional sensors try to underexpose and then pull the brightness back up.

同时，由于相机始终保持在ISO200，也不象普通传感器那样尝试欠曝光而后期补光从而付出引起噪点增加的代价。

But shooting the sun is tricky. On a clear day, the sun is so bright that your camera's meter will tend to underexpose everything else in the frame. Shoot in manual mode, or take a reading without the sun in frame, depressing the shutter button halfway to hold the exposure, then reframe before you shoot. If you're shooting film, bracket a lot to make sure of getting the exposure you want.

把太阳放在构图中以表达沙漠中的高温和荒芜，但拍摄太阳比较麻烦，晴空下的阳光影响相机的感光计，以至于构图中其它部分曝光不足，为避免这种情况，要启用相机的手动模式，或者是将太阳从构图中排除后，半按下快门固定曝光值，然后重新选择有太阳的构图，将快门按到底。

Think about including the sun in your photograph—it's one sure way to say hot and harsh. But shooting the sun is tricky. On a clear day, the sun is so bright that your camera's meter will tend to underexpose everything else in the frame. Shoot in manual mode, or take a reading without the sun in frame, depressing the shutter button halfway to hold the exposure, then reframe before you shoot.

The basic concept of FOP can be summarized as to further optimize effective prescription according to the standard of curative effects and with the aid of modern science and technology and theories of traditional Chinese medicine.

其基本内涵可概括为：以确有疗效的中药复方为研究对象，以现代科学技术和传统中医药理论为技术支持，以该复方所治病证的药效响应为评价标准，以优化重组疗效更优的新复方为研究目的。

Ever since our world has been a world, native forests have been indiscriminately exploited by man.
