Google is giving away its Nik Collection of filters, this is handy if you use Photoshop etc type programs as it imports the Nik collection into the program.
This program Cost $500 back in he day then Google bought them out and offered the filters for $150, and for some reason they have now offered it for free, I am not grumbling as there are some superb filters in there to make your photo's stand out.
