If you've bought a Nik product before, check your spam filter/box. I got mine. Free. Holy frickin' sheet. I was gonna pay the $130 for the package--and it still would've been cheaper than what I paid for upgrading from Viveza to Viveza 2.
This is powerful, versatile software folks. The entire package used to run $500+ (and they didn't give academic discounts on the package, because the separate components totaled over $800).
I like Imagenomic better for noise reduction and even for their Portraiture tweaking, and Topaz makes some good plug-ins, too, but the entire Nik plug-in package for less than $150??? Do it. Do it now.
