NIK software, when it was first introduced years ago, was expensive but worth the cost because of the power of the effects and the ease with which it integrated with software like Photoshop and Lightroom. Google purchased NIK a few years ago has recently made the entire suite of effects available for free.
If you think you need Photoshop or Lightroom to run these filters, you don’t. These filters can run independently on either a Windows PC or a Mac, or can be called from some imaging programs (like FastStone Image Viewer for Windows PC’s).
There are many great programs that do similar things with images. Some are inexpensive, others are not. Up until now, one could say you get what you pay for, but Google has changed the equation on this. One has to wonder what they are up to…but, for now, this is a great deal.
