Recently, Google released a new app to make the Google Photo experience even better. The app is PhotoScan by Google and it allows you to move your print images to the digital world! Using the app, you simply snap a picture of your picture, rotate your phone following the onscreen prompts and your photos are automatically cropped, rotated, and color corrected. Photos can be saved to your camera roll or sync to your Google Photo account (and if you aren't using Google Photos, then you may be missing out a photo storage solution that changes the way you interact with your photo memories). PhotoScan is both an Android and iOS app. You can read more about this app here.
If you would like a quick tutorial video, I've created a quick screencast to show you how to use this scanning tool .
