Nik Software produced one of the best regarded photographic post-processing software packages available, and the company subsequently became part of Google in 2012. A few days ago, Google announced that it’s making the Nik Collection available free of charge. I’ve never tried the package myself, but if your computer and software meet the minimum system requirements (including which versions of Adobe software you’re using), it could be worthwhile investing some time and effort into trying out the Nik Collection.
