There are no new plug-ins in the Nik Collection 6 this time around, but significant feature additions to some and improved local adjustment tools across the board.
Dfine (Nik Collection)
Software plug in for reducing noise in images and part of the Nik Collection. Like many other noise reduction programs, Dfine analyses the image and calculates a noise reduction profile. It’s also possible to define the areas used for analysis manually.
DxO Nik Collection 5 review
Verdict: 5 stars Only a modest amount has changed here from Nik Collection 4, but it was already so good there was little room left for improvement. If your photography needs an injection of inspiration, style, or creativity, this is where you’ll find it. Even if you already have version 4, the new Color Efex Pro 5 and Analog Efex Pro 3 could make it worth upgrading.
