Where I found a bar code, I simply pointed the phone's camera at it, held still for a moment and Google Shop automatically scanned it and found the exact right results.

当我发现一个条形码时，我将我的手机摄像头对准这个条形码，保持几秒，之后，谷歌Shopper就会自动扫描，然后寻找精确的结果。

If you have a high-end camera, the lens probably has screw threads, which means you can add a UV or Skylight filter (available at your neighborhood camera shop).

如果你有一架高档相机，那么它的镜头上可能有螺旋纹，这表明你能增加一个紫外或者天窗过滤器(附近的相机店里有售)。
