Sam, the best deal is to get the bundle of all three. I think it's $239.00. Much cheaper than buying them individually. And, you professional photographers would like get SOOOOO much more out of them then I do. When I run the filter, a dialog box comes up with an infinite amount of adjustments you can make, and I don't ever do any of them. I have always gone with the default and clicked OK. LOL I can only imagine the possibilities!
