If you have a large collection of old printed photos, you can digitize them using a scanner attached to your computer. However, the easiest and cheapest way is to use a photo-scanning app like Google PhotoScan, Microsoft Office Lens, or TurboScan to help scan, rotate, crop, and add filters to your photos.

如果您有大量的旧打印照片，则可以使用连接到计算机的扫描仪将它们数字化。 但是，最简单，最便宜的方法是使用照片扫描应用程序(例如Google PhotoScan，Microsoft Office Lens或TurboScan)来帮助扫描，旋转，裁剪并为照片添加滤镜。

Despite the benefits of using an app, be aware that it may not be the best choice in every situation. The main drawback is that the overall picture quality and resolution achieved through a mobile app won’t compare with what you can get from a dedicated scanner. You also won’t have access to advanced settings like output file type, color mode, resolution, size, brightness, and contrast with an app.

尽管使用应用程序有很多好处，但是请注意，它不一定在每种情况下都是最佳选择 。 主要缺点是通过移动应用程序获得的整体图像质量和分辨率无法与专用扫描仪获得的图像相比。 您也将无法使用应用程序访问高级设置，如输出文件类型，颜色模式，分辨率，大小，亮度和对比度。

Instead, a mobile app comes in handy if you want to scan a collection of photos quickly and don’t need top quality or resolution. You also won’t need to deal with connection issues or tricky scanning setups; just point and scan. Here are several photo scanning apps and a look at how they work.
