The PhotoScan app opens up your smartphone camera and asks you to position a printed photo within the frame. After you line up the printed photo within the frame, you will need to tap on the shutter button. The shutter button triggers the flash and shows four white circles on the corners of the printed photo. Once you hover your phone camera above each white circle, PhotoScan will automatically crop, remove the light glare and enhance the photos. And after the photo is processed, you can manually adjust the corners and rotate as necessary.When you are finished digitizing your photos, you can save all of the scans to your camera roll with one tap. After the photos are added to the camera roll, you will see a confirmation and a button to open the Google Photos app where the scans can be viewed.
