I don’t use PS, but probably this will just take me back to the TIFF generated by Nik, without any info about how it was processed in Nik. It’s just like going back to Nik generated file, with no info on prior Nik edits. Since Nik is not only about LUT-like editing, it may be far from satisfactory. Another point is that after some time you may want to know how you got this result from SEP. For a newcommer it certainly won’t be easy, but I suspect that even experienced people might have problems to reproduce some creative edits in Nik…
