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.
HDR Efex Pro (Nik Collection)
HDR Efex Pro is a software plug-in for creating HDR (high dynamic range) effects from single images or bracketing sets of exposures. It's part of the DxO Nik Collection. You can apply preset HDR styles with a single click or adjust and make your own effects using extensive manual controls.
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.
