text: Now I’ll have a look at the B&W profiling, since it’s essentially the same process, with a few different options.
  The first chart is the same, but the second chart immediately shows three columns of uniform colour at different brightnesses. These help refine the B&W and near neutral behaviour of the profile.
  When it comes to naming the profile, I get several ‘style’ options which reflect different uses for the profiles.
  You still have measurement data and can build profiles of all four other B&W types just by selecting a style and providing a new (unique) name.
