我承认我是菜鸟请高手们别笑哈

我用的是Nikon的d40，我发现了问题。
一般在auto/auto without flash的mode拍照白天、晚上只要光线不是很差效果都不错，可是用M, A，S mode就不行了。
比如光线很好的时候（阳光明媚的时候）我用Manual Mode拍，把快门和光圈调到正常曝光的位子（就是显示曝光刚刚好的位子）找出来的照片是正常曝光可是光线比较暗的时候（也不是很暗，就想多云的时候）我要调到同样的位子就曝光不足了，要调到显示曝光了才能有正常颜色的照片，要不然就太黑了。

还有有时候光线很不好的时候（比如晚上室内，开着灯的时候，其实也不黑）就完全调不到正常曝光，一直就显示曝光不足，不管怎么调快门光圈都是曝光不足。。。可是在auto/auto without flash就一点问题也没有。。。

最郁闷的是我看了auto without flash的快门和光圈数字我用manual调到一样的可是就会曝光不足。。。

所以问题是auto能拍出来表示不是光线的问题。。。可是为什么会这样呢。。

高手们帮帮忙吧~

you need to understand the three important relationship, ISO, Shutter speed and Aperture...
learn to take picture using Manual mode.
- ISO - sensitive to light, the higher ISO the more sensitive but higher ISO has grain problem
- Aperture - allowing how much light to enter into the sensor, the smaller the value F-stop, the more the light
- Shutter speed - allowing how long the light to enter into the sensor, faster shutter is used during daytime when light is bright, slower speed when light is low

- for shooting night picture, if very low light, use higher ISO to pick up more light or use slower shutter speed, try to use tripod if u can. take some pictures and change the setting, experiment different setting ;loveliness;

I understand the logic behind this but the main problem is why is it showing normal exposure when the actual exposure level is not correct. Also how do I take photos in manual when the light isn't bright when it seems impossible to adjust it to normal exposure no matter how i adjust the shuttle speed or aperture? Will adjusting the ISO help?

put your camera on a tripod, set the shutter speed to 1 second or more and try...
- set your aperture or f-stop to the max

take the camera exposure meter as a guide, sometimes it is not 100% correct... take a picture then adjust the setting accordingly... ;loveliness;

帮你顶一下,你调自动模式了,那么ISO也是自动的,所以^^^^^^^^^^^^^^^^^^
