Improved an over ISO sensitivity gain.
改进了对IS O感光度收益。
By any sensible, practical standard, at the low end of its ISO sensitivity scale the A77's image quality is very good.
从明智、务实的标准来看，A77的图像质量在IS O感光度规模的低端非常好。
ISO is a rough measure of sensitivity to low light.
ISO大致是在暗光下对光的敏感程度。
If star trails are desired, using a large aperture and higher sensitivity (ISO 200-400) can enhance the brightness of each streak.
如果需要星光轨迹，那么使用大光圈和较高感光度(ISO 200- 400)就能提高每条轨迹的亮度。
This is extremely important, because it determines how fast and at what light sensitivity (ISO) your camera can shoot in different lighting conditions.
光圈非常重要，因为它决定你的相机在不同照明条件下拍摄速度有多快，以及拍摄时的感光度(iso)为多少。
You will often find yourself alternating between low light and daylight, so make sure you reset the ISO to the lowest setting immediately after you have finished shooting at a higher sensitivity.
你常常会在微弱光线和日光下变换拍摄，所以当你用高iso值拍摄完毕后，一定不要忘记马上把它调回最低值。
Light is scarce indoors, and at a high sensitivity like ISO 800, your camera doesn't need as much of it.
在缺乏光线的室内环境中，如果使用高感光度如iso 800进行拍摄，那么你的相机将不再需要太多的光线。
