Verdict: 5 stars Out of the seven different Nik plug-ins I get most use out of three or four of them. But for me, those three or four plug-ins easily justify the cost of the Nik Collection on their own. They don’t just offer tools you won’t find anywhere else, they make them easy to understand and apply with almost infinite variety. The Nik Collection deserves to be considered one of the key editing tools in digital photography.
