Though I have checked the box "Create Smart Object" in NIK HDR Efex Pro 2, there is no Smart Object Layer created. It must be something in the CS6 settings, but which?
Wat I do: I open CS6, press File>Automate>Merge to HDR Efex Pro 2. Choose multiple images and make sure the Create Object box is clicked. Make my edits in the HDR Efex Pro 2 interface. Then choose OK. What I then get is my image in a Background layer with a lock icon on it. It's a 16-bit RGB TIFF, not a 32-bit Smart Object.
Smart Objects work everywhere else. With Silver Efex Pro for example, from ACR, and I can open images too as Smart Objects.
Any ideas? I am not really a pro in CS6 and use Nikon Capture NX2 as my RAW editor. Any help would be appreciated.
