Another suggestion, I have found useful is to place a sheet of black carbon paper (remember when we all used this for our letters?), behind the original item, this makes the original slightly darker. I have never tried these two in combination. I have noticed that some of the Record Office fiche/film readers, do have a yellow strip across the viewer, which can be set to align with any line on the original, this certainly improves the image quality.
