Just take a couple of pictures of an evenly illuminated surface like the sky at dawn/dusk or a white laptop screen or lightbox, EL-sheet, etc... There are many ways to do it. Search on these forums for lighboxes, etc... There's a basic tut on flat fielding in this site resources and articles section.
