You heard right, Google has dropped their Nik collection suite down from $149 (roughly £105) down to 0$, completely free! (which you can download here), as well as if you have already paid for it, you should receive an automatic refund.
The Nik Collection is comprised of seven desktop plug-ins that provide a powerful range of photo editing capabilities — from filter applications that improve color correction, to retouching and creative effects, to image sharpening that brings out all the hidden details, to the ability to make adjustments to the color and tonality of images.
