Comments:
An interesting test revealing some pleasing and attractive colours after applying 'Levels' > 'Auto'.
The black & white result isn't dissimilar to one from a normal, 'straight' colour file with black & white conversion. The range of tonality could readily be adjusted for personal expression.
