Nik Software of course was bought by Google. It is no longer available on CD's and now Google has the whole collection for $149usd. I think at one time the complete collection was like $400 usd. I believe it will only function as a plug in to Photoshop, Lightroom or Aperture and not as a stand alone program. Still, Nik effex always seemed like pretty good software and this price seems really good. I may have to give it a go. There is a 15 day trial of course to try it out.
