I decided to change the angle yet another few degrees to show more of the board.

Our goal is to have the surrounding space pure white (RGB 255 255 255). In the above picture it is not yet white enough:

That's basically it. Now, it could happen that your object itself is too bright or dark now. You can adjust it here:

Use the Gamma slider to adjust to your needs. I tuned it down a bit to get more contrast:

The final picture

So, after doing all that in a few easy steps, the result looks like this:

Easy enough, right?
