1. A method of enhancing imaging of a document that includes content on a medium, comprising: capturing a first image of the document using monochromatic light at a first wavelength; capturing one or more additional images of the document using monochromatic light at one or more different wavelengths than the first wavelength so as to image a surface texture or additional features of the medium; and combining the first image and the one or more additional images to generate a greyscale image, wherein combining the first image and the one or more additional images results in subtracting a texture from the first image.
