These galleries show the effect of scanning with a filter that “sharpens” the image. It appears that not using the filter at all results in a muddier, inferior image. For our purposes, there does not appear to be much obvious difference between Low, Medium, and High. All images were scanned at 600 dpi. The files are bigger than we want, so we will redo the test at 300 dpi to compare and make sure that if we drop down to 300 dpi we are not sacrificing much..
