How to clean up a whiteboard photo using GIMP

Skipping other possible actions, such as perspective corrections, here is how:

  1. Duplicate the base image layer.
  2. Set the new layer's mode to "Divide".
  3. Apply a Gaussian blur with a radius of about 50 (Filters/Blur/Gaussian Blur...).

If you need to manipulate the resulting image further, create a new layer from visible (Layer/New from Visible).
