PhotoLab/FilmPack compatibility

Hi.

I used a FilmPack-based preset (Constant Puyo) in PL 9 on a photo.

I then loaded that now sepia-toned image into Nik for added edits.

Nik Silver Effects won’t keep the toning, and forces the image in B&W. I managed to add a few effects with other Nik (Analog and Color), but I am surprised that Sepia is not compatible with Silver Effects.

Or am I missing something?

TIA.

Pretty sure that is by design. As a dedicated app for the sole purpose of converting and editing a black and white photo, I believe it is behaving exactly as intended. That said, once the image has been opened in Silver Efex, you can then add sepia toning.
