Scanning photos into digital copies is not just for old photo albums. Nowadays, you often have to decide if you want to buy an expensive digital version of school photos, not to mention weddings. But why spend more when you have a photo scanner in your pocket?
Google PhotoScan is an app for Android and iOS that lets you capture multiple photos from a print photo using the camera on your phone and merge them together using intelligence and mark the edges of the photo. The photo stitching feature also eliminates glare from your phone's flash, though a well-lit, natural-light photo provides the best results.
To be fair, a native digital image delivers the clearest and sharpest results. If you have a dedicated scanner or a multifunction printer with a scanner connected to it, you should definitely check this option. But scanners cost money, as do the rights to digital images ̵
(Make sure you know the rights to share these images and know if the photographer is claiming rights to the photos in question.) If you've taken the photos in question yourself, you should be fine.)  How to Scan a Photo Using PhotoScan in Three Easy Steps
Download Google PhotoScan for Android or PhotoScan for iOS first. Google does not limit what devices you can use with PhotoScan even though you need Android 5.0 (Lollipop) or higher. Of course you need a photo, whether shiny or not. Google does not seem to have set any size limits, though I only used smaller 3×5 and 4×6 prints.
Second: Start scanning. When you launch the app, PhotoScan shows you what to do: capture the entire printout within your camera. PhotoScan then overlays the print image with four smaller circles and prompts you to move the PhotoScan crosshair over it. (Again, the short tutorial clarifies).
Don Do not worry if you do not aim the target crosshairs exactly at each of the targets, as it does not seem to make any difference in the clarity of the final image. The circles tended to jump a bit as I straightened them too.
With PhotoScan you can also define the corners of the image after the image has been taken. This only came into play when I used PhotoScan with a print set against a light background, making it difficult to distinguish the edges.
What apparently affects the picture, however, is the lighting. I shot the same photo in an unlit, draped room and used the light from my phone to light the picture. I then went outside and photographed the same print in the shadow of the afternoon with distinct color differences. The outdoor look seemed a bit washed-out in places, although the color seemed to be livelier. It might be worth experimenting to find out what works best. Note that there is a "magic wand" icon that lets you enable or disable PhotoScan to compensate for the camera's flash.
PhotoScan also seems to decrease the resolution. Although I took the photo with a 12.2-megapixel camera with Google Pixel 3, the scanned photo was saved in a resolution of 3,000 x 2,000.
Third Post-processing . Was just a joke! At least in the PhotoScan app there is no third step. PhotoScan saves the photo on your phone so it can automatically be backed up in Google Photos, Microsoft OneDrive or Apple's iCloud. Post-processing – adjusting contrast, color, or red-eye effects – must be done using an app such as the Windows 10 Photos app, Google Photos, Lightroom app, or similar.
Done. PhotoScan is easy and intuitive to use. Try it with an old photo. The results can surprise you – and are good enough to save money on future photo shoots.
