Let's scan that document you have in front of you by clicking the floating button at the bottom right, and selecting the scan option.
The camera will open, and you'll now be ready to center the camera over the document. Try to get everything in the camera viewfinder so that the edges are touching the edges.
The best way to get a shot is overhead. If you aren't used to doing, take multiple shots and keep the best one.
The next screen is where all the magic happens; you'll be able to crop, rotate. The colour pallet lets you choose between black/white or colour.
Satisfied with the way the document looks? Good! You're ready to hit that save button. Google Drive will automatically save the document to your drive folder. The best thing in all this is you don't even have to copy, move the file anywhere it's already on your cloud. You can now access this file from any of your devices.
