ViewPoint, yes. It is a Photoshop plugin, but PhotoLab is not a Photoshop plugin. If they did something like they did with Lightroom for Photoshop that would be a help.

Yes, and that is what I currently do, export either a dng or a tiff, and send it to Photoshop. But that makes PS an external editor for PL, it does not make PL a plugin for Photoshop. My thought was that Dxo could generate a lot of business from Bridge, Lightroom and Photoshop users who are not currently using PhotoLab if they created a Photoshop plugin or if they made PL accessible through the Photoshop Automation interface.
I really like PhotoLab and have been using it, and Optics Pro before it, since perhaps version 6, but Dxo has been having financial troubles and I thought that creating a PS plugin would be another revenue source for them.
