Google wants to help get the old photos stuck on your fridge onto your phone, where you can save, edit, and share them.
Position your phone over a photo and tap PhotoScan's capture button. The app does its best to identify the four corners of the image, and then you follow an arrow to navigate your phone over the four dots displayed on the screen.
After you complete the capture, PhotoScan gets to work, modifying the image to remove glare, straighten it, and crop the edges.
You need a steady hand to capture an image, and the results are not always perfect. The app can sometimes misread the edge of the image, either leaving too much of a border or cropping out part of the image.
Google Photos' updated editing tools
PhotoScan comes with a few simple tools for adjusting corners and rotating the image. But if you want to do more serious work, this week Google also released an updated set of image-editing tools for Google Photos, including an improved auto-enhance tool that does a better job of balancing exposure and saturation. Twelve new filters change the look of feel of your images. And new Light and Color tools help you fine-tune your images. The update to Google Photos is available on Android and iOS devices and via the Web.
