I paid $134.25 for this a few years ago! The collection includes- Analog Efex Pro, Color Efex Pro, Silver Efex Pro, Viveza, HDR Efex Pro, Sharpener Pro and Dfine.I use the Silver Efex Pro for excellent B&W conversions, I feel it offers better results and is easier to work with than Lightrooms own B&W options/presets. A recent instagram shot I used Nik Silver Efex Pro to editThe rest of the set is pretty handy too - Go grab it for free now. Google Nik Collection. I do worry that this means we won't see much development on this in the future now that it is free. It would be interesting to see more of these tools be bundled into Google Photos. If you did buy Nik this year Google will be refunding your money.
