Just in case anyone wanting to use the Nik Collection and I would strongly advise people to do so as it's exceptional value for money (free), but don't have Photoshop or Lightroom as it's a plug-in, there is a way to use this software. Rather than my trying to explain just follow the link.
Believe me it's well worth while, I run all my images through Nik, just follow the link.
