DxO Nik Collection 3 is the company's biggest update yet to the Nik plug-in suite. The new Perspective Efex plug-in is a really welcome addition, and while you no longer get PhotoLab Essential included, the purchase options are a lot simpler now. The new non-destructive workflow system works with Lightroom and any other program which can use the Nik software for external editing, and it's very clever, even if the files are quite big.
