Among the questions that roil my mind every now and then is: "Why don't the main photo editing applications come with a decent set of virtual photo filters? A polarizing filter -- is this too much to ask?"
Tiffen, one of the leading makers of actual glass photo filters, comes to the rescue with Dfx Digital Filter Suite, a collection of filter effects that covers pretty much every base I can think of, from infrared to bronze glimmerglass. It works with Windows and Mac, as a standalone app or a plug-in for Photoshop and various video editing apps. Pricing ranges from $100 for the "select" version to $600 for an edition bulked out for video editing.
