If I opened Color Efex or Silver Efex via the Filter menu in Photoshop the changes are not applied to the picture to a separate layer. When I use the filter via the Selective Tool palette or if I use it to an smart Object everything is working fine.
The other filter, like DFine, Analog Efex and Viveza are working via the Filter menu.
A reinstallation of the Nik Collection doesn’t help.
Win10, Ps 24.5, Nik 6.0.0. Settings applied to separate layer.
