Sadly not.At that price $100. for the bunch
There are six products which retail for $199 each for Silver Efex Pro and Sharpener Pro, and $99 for the other four. That's a total of $800. You can buy the lot as a bundle if you only want to use them as plug-ins with one product (i.e. Lightroom, Photoshop or Aperture), for a price of $300.
So if one is thinking of buying Silver Efex, then you get the remaining $600's worth of software for $100.
Still a pretty good deal
I have saved a lot of study time by using NIK software, but I have also taken most of their tutorials. The use of the different plugins will not only help in the processing, but if you are interested in stylizing you image(s), there is great opportunity to do so with NIK.
BTW: I love, love, love NIK software and its capabilities!
I am wondering if Google decides to drop NIK, will onOne software step in??? Maybe, maybe not. But there is interests between the two parties.
