Camera Lens Filter Guide
Though many filters can be replicated in Photoshop, several should still be in your bag. Have them ready, learn to use them and you can bring your images to the next level. The adage “You get what you pay for.” holds true when buying filers. The moderate and more expensive filters will be of much higher quality. When buying filters, look for coated or super-coated filters. For round filters, Tiffin and Hoya make good filters at reasonable prices. B+W and Heliopan are excellent, but a bit more expensive. For square or rectangle filters (NDG or ND Filters) Singh-Ray, Hi-Tech, Lee all make very high quality filters.
