After reading the follow-up comments to my re-invigoration of the “Do I need NIK?” thread, and following links to other, earlier discussions, I decided to try a few things I had seen to get a more intense result on a photo.

This used a film emulation from FilmPack as a starting point (I like the Ilford ones), then I applied the upward tone curve to emulate Nik’s ‘boost’ type of functions, as shown in one thread by @Joanna.
This aircraft was striking with it’s highly polished metal fuselage, so it is fitting that it really shines in this B&W render.
