Each time when it comes to this topic, the same discussion starts again, which honestly is completely unnecessary. Everybody does as he / she likes, based on habits, knowledge … or just on personal preferences.
My goal is printing usually for myself, which means concerning the file size I produce ‘limited’ output. I’ve never relied on a raw-converter’s output only, but edited / tweaked the file for the intended purpose and kept the versions (or with ‘alternate’ layers) – and when optimized per print size (layout) and paper the digital counterpart for the print out.
With all that, the necessary conversion from RAW to TIFF doesn’t count for me as much as it might do for others, while a seamless integration of the Nik filters in PL would help at any time.
