Camera lenses have two general attributes: f-stop and focal length.───照相机镜头有两项一般属性：f制光圈和焦距。
A large opening (small f-stop number) gives you a very shallow DOF, and a small opening (big f-stop number) gives you a much deeper DOF.───一个大洞的开启(小f值)会带给你浅度景深，而一个小的开启(大f值)则会给你一个深度景深。
These tags, called EXIF metadata, specify things like the exposure and f-stop settings, gps information if your camera has it, and, of course, the time and date the photo was taken.───这些标记称为EXIF元数据，是为了说明照片的曝光度和光圈设定，有的相机还会显示GPS信息，当然，还有拍照的时间和日期。
We had to adjust the f-stop of our cameras relative to the sun line for every photograph we took.───我们每照一张相片，就必须依据相机和太阳光的相对角度调整光圈值。
If you want the scene to look like it's a half-hour later, stop down by one f - stop, or set exposure compensation to minus one.───如果你希望照出来的效果如同半小时之后的样子，可以减一档光圈，或者减少曝光补偿。
But it's just nice to know which f-stop to choose when your main concern is sharpness, not controlling depth of field.───如果主要考虑的是照片的锐利（清晰逼真）而不是景深，那知道你的镜头的最佳光圈很非常有用。
The larger the aperture (remember, that means the lower the f-stop) the smaller the depth of field.───越大的光圈（记住，f值是越小），景深越小。
Remember, going up an f-stop cuts the amount of light by half.───记住，调高f值是减少光线量的一半。
