Option A: Using your phone’s camera
Many people find this way easiest and you'll get better results. You can use just the camera, or better still an app that makes it even simpler. Let's cover the camera way first.
The phone must have a camera built in and be able to use the internet. Give the camera lens on the back of the phone a quick wipe over to remove any fingerprints. Place the photo on a flat surface under good light, but without any reflections or sunlight streaming across it. If it is in a photo frame, please remove it before taking the picture to avoid any glare from the glass. Make sure to have the automatic flash on your camera phone turned off.
Hover right above the photo with the camera so the screen shows the picture looking square on your phone screen, then resting your elbows to keep your hands as steady as you can, take a photo of it. Please ensure the whole photo is captured in the image you’ve just taken.
If you know how, then please set your camera to take pictures at a high resolution and use the jpg or jpeg format. If that sounds a bit confusing, don't worry and just take the photograph anyway.
If you can put an app on your phone, then there's an even easier way and the results are always the best. It’s a proper Google app so you know it will be very safe. It’s called PhotoScan and you can download it from Apple's App Store, Google Play Store or https://www.google.com/photos/scan, where you can also see a video showing how easy it is to use.
Option B: Using a flatbed scanner/printer
(If you aren't accustomed to using a printer or scanner it might be best to use the first option which will still give great results.)
Set the scanner to work at a high resolution, preferably 600 dots per inch or higher for A4 size. Wipe over the bed of the scanner with a microfibre cloth to get the best image quality. Place the photo on the glass plate face downwards. Scan and then save it.
Keep following these instructions above until all of the old photographs are ready.
