Viewing the PL5 user guide (PDF document) and searching for the word FilmPack will highlight descriptions of the added functions. Or just look through the filters and palettes in PL5 to see most of the extra adjustments grouped together. There might also be something in the FAQ list for PhotoLab or FilmPack on their respective support pages, but you’d have to search for it.
Yes, I know what it is, and how it works, but from the user perspective the Time Machine looks and operates like a separate module with a very specific purpose as well as its own interface. It is therefore, in my opinion, a separate feature. Every review of FP 6 highlights the Time Machine as a feature.
One tool that hasn’t been mentioned is the Filter tool, which allows us to emulate the placing of a physical coloured filter in front of the lens - once again, for B&W work.
Being an LF film photographer as well, I will tend to use that before moving on to the Channel Mixer as, sometimes, it is all that is needed.
I tend to apply them at around 5-20% intensity. Warm and Cool change the overall color temperature in ways I like. I also use Mauve and the more subtle Orange filters to adjust the look of landscapes so that colors are more in balance/complementary. Some of DxO’s own presets use them for color images, too: it was when I noticed one applying 5% red that I got more interested in doing this on my own.
