Hehe… I am an Adobe person. I don’t even know Nik Collection by Google until today. What is Nik Collection? It 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. And Google makes it as free from today onward. Yes, all applications like Analog Efex Pro, Color Efex Pro, Silver Efex Pro, Viveza, HDR Efex Pro, Sharpener Pro and Dfine are free to download now.
