This chapter covered some of the plug-in filters available in Elements. These filters can be applied to an entire image or to selected parts of it. First, you learned about the Sharpen filters, including Unsharp Masking, to take the blur out of digital photos and scanned pictures. Then, we looked at the Blur filters. We also explored an array of artistic and, well, interesting filters with the potential to transform a regular photograph into something truly unique, and maybe even beautiful.
