This information applies to the latest version.
In earlier versions, DxO FilmPack was available as an Adobe Photoshop plugin through the Filter menu in a separate window. Starting with the latest version, DxO FilmPack has been redesigned to integrate directly into the Photoshop interface - just like Nik Collection 8.
You can now access DxO FilmPack tools from the Photoshop panel.
This streamlined integration lets you apply DxO FilmPack looks more quickly, without leaving your Photoshop workspace.
