The Nik Collection is a suite of seven desktop plug-ins for photography and is popular among professional photographers. The Nik Collection which used to cost $149 for download has been made free by Google starting today. The Nik Collection was developed by a German developer also named Nik and retailed for $499.95. Google had acquired Nik’s tools for its mobile editing app Snapseed and reduced the price from $499.95 to $149 then. The Nik Collection has since grown from six to seven plug-ins. It includes Analog Efex Pro, Color Efex Pro, Silver Efex Pro, Viveza, HDR Efex Pro, Sharpener Pro, and Dfine, all of which work in Photoshop, Lightroom, and Aperture. All these plug-ins which were a domain of professional photographers earlier can down be downloaded for free. If you are a photography junkie, you can download the entire Nik Collection here. Google also stated that those who had paid $149 in 2016 for the tools will be automatically refunded.
