I can't open Tiff in Dfine, but in Silver Efex


I want to open a tiff file in Define, which I can open in Silver Efex. The same photo.
The massage is: File is not supported, the same problem in Sharpener.

Is the TIFF file compressed? Some NIK programs don’t like compressed TIFFs, try an uncompressed TIFF and see if that works.
