Google has dropped the price of the Nik Collection, a suite of seven desktop plug-ins aimed at advanced photographers, from $149 to nothing, the Verge reports.

The Nik Collection first came under Google's stewardship when the company bought German developer Nik for its mobile editing app Snapseed; Google later dropped the price from $499.95 to $149.

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. You can grab the collection, and anyone who bought it for $149 in 2016 will be automatically refunded, the Verge says.
