Well, I’ve spent the past couple of years testing a number of apps under different conditions and here are my top 5 tips:
1. Hold the phone flat in the palm of your hand
This helps to steady the camera and minimizes any shadowing, particularly if you are in an area with bright overhead lighting.
2. Use a contrasting background
It helps to differentiate the document from other surfaces and makes it easier for the sensors to identify the edges, meaning no need to manually crop the page.
3. Use auto mode
Lets the camera do its thing and take the crispest image.
4. For extra quality, dial up the dpi
Use 200-300 dpi as a minimum. The final file size will be larger but the documents will be much better quality.
5. Check the images
Make sure that you have all the pages, that they’re in the correct order and have been cropped and rotated correctly and that nothing has been lost during the scanning process e.g. headers, footers or water marks.
That’s it. Easy! There are many, many scanning apps out there. Find the one that works best for you. For me, image quality and document security and confidentiality are vital. What do you look for?
