查询词典 exposure meter

From judging proper shadow, midtone, and highlight values to how to meter for proper exposure, you will see "first hand" how to do it yourself.

从判断适当阴影， midtone ，并突出价值，如何进行适当的曝光米，你会看到"第一手"怎么做你自己。

Would you need a 12% gray card to get the correct exposure using an ANSI calibrated meter (i.e., is the luminance setting for ANSI really equivalent to 12% reflectance?)?

那么我们是否需要一个12%的灰卡来得到一个正确的曝光值，当我们使用的是ANSI标准的测光表？

Transport should be the prevention of weight, fall behind, hook thorn; storage should be to prevent exposure, more than 1 meter away from the heat source.

运输时应防止重压，抛摔、钩刺；贮存时应防止曝晒，距热源1米以上。

Micro-computer monitors work inside the electron gun to emit electronic, through the acceleration of high-voltage electrode, adjust shooting at the screen, the screen of fluorescent material by high-speed electronic flow impact, resulting in X-ray, scientific evidence shows that more than 20 of each year only Guoqin dose of radiation, will constitute a harm to humans, operate microcomputer year will not be more than 0.3 Roentgen of exposure; even when engaged in computer work for 30 years, the cumulative exposure will not be sufficient to cause human injury lowest half, but during early pregnancy (the first 3 months) the fetus is in a cell division, organ differentiation sensitive period, or should be:(1) hours of work per week is not more than 20 hours (2) one meter away from the computer (3) wearing protective skirt (4) work completed Huanyi bath in order to reduce the electromagnetic radiation on the impact of the fetus.

微电脑显示器工作时，内部的电子枪发射出电子来，经过高压电极的加速，调整射向荧光屏，屏幕上的荧光物质受到高速电子流的撞击，产生X射线，科学论证表明，每年只有超过20论琴的剂量照射，才构成对人体的伤害、操作微机一年也不会超过0.3伦琴的照射量；即使从事微机工作30年，累积的照射量也不足以造成人体损伤最低值的一半，不过妊娠早期(头3个月)胎儿正处于细胞分裂，器官分化的敏感时期，还是应当：(1)每周工作不超过20小时(2)距电脑一米开外(3)穿防护裙(4)工作完毕洗澡换衣，以减少电磁辐射对胎儿的影响。

In other words, we would still need the same exposure, regardless of the variation in our camera's light meter reading.

尽管测光表的读数边了，但我们需要的实际曝光量是没有变化的。

Light meter : An electronic device used to measure the amount of light available for making an exposure.

测光表：量度光线强度以计算摄影所需的曝光时间的电子仪器。

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.

More importantly, the underlying features are well done, so that it's easy to get good picture out of - the autofocus is pretty sophisticated, reliable and easy-to-use and in difficult-to-meter situations, the camera's exposure errs on the side of underexposure, to prevent detail being lost.

最重要的是，下面的特点是如此优秀，所以在自动对焦也可能很高的出片率，精密、可靠而且易用？？？？？，它宁可欠曝也不过曝引起细节丢失（译者注：欠曝是可以通过PS修补的）。

After 100 hours exposure to a fade-o-meter, reflection factor may not be less than 85%, and finish can show no visible color change.

a。初始反射率不得低于86％；暴露在空气中100小时后，反射率不得低于85％，表面涂层没有可见的颜色变化。

Means the parent directory, so this command means to execute "toolchain.sh," which is in the current directory.

代表父目录，所以这个命令就是执行当前目录下的"toolchain.sh"。

Yes,In fact,I'm on our city ream.

是的。事实上我是我们市队的。
