DNG format from Mavic 4 pro mini works in LR Classic in some of Nik 8 but not HDR EFX

[pierre5018 (PIERRE LABRECHE)]

I had created a request for allowing DNG files as input to Nik Collection.

Nik Collection : process dng files. in particular those generated by Photolab

This will be particularly useful for dng files exported by Photolab 4, but not only those. Thanks

The DxO support site states :

Which file formats are supported for use with Nik Collection?

Are you sure that Nik 8 modules accept DNG files directly ? Have you checked that it is not the embedded jpg preview that is read in ?
