The program works with Lightroom 5 and they are both on a pretty solid footing, but when it comes to the color correction features of the plug-ins, Nik Software is lightyears ahead of most other stand-alone plugins that try to replicate its look. Now, unlike say, Nikon's Nikon Capture software, it doesn't make you pay $300 for the good stuff contained in the Nik Collection.
If you're pricing this software, I'd say you're charging what you would to sell a photography magazine subscription. They all charge about $250 per year, and it's easier to say -thabanks, but no, so I noticed. Although absolutely non-professionals use the program and other than the interface its similar to what was previously available through subscription, I wouldn't pay $650 for the software, especially since it's good in CS5 and 5.5. I would only spend more around $2000. Because it was so expensive, I only bought the collection of plugins and not the individual ones, hence only have point snip then 25% for the collection, but I think they're all worth it. If I was a professional it's hard to imagine I would spend that on plugins alone.
I've seen a lot of people complaining it was working with CS6 as well as CS5, but when I purchased it, I was given a download voucher, which I redeemed. I expected it to work with the older versions, but I was delighted to find it working just fine with CS5, CS5.5 and CS6 (as well as with Lightroom 5.2). I find it's value lies in the introductions of Creative Suite 6 and Lightroom 5 and also in the addition of a new feature called Color Efex Pro 2.0. In addition you get a collection of individual plugins. d2c66b5586
