N+2 development raises the contrast, but in terms of
local contrast it does so only within a narrower band
of midgreys. The shadows and highlights may actually
get their local contrast reduced by being blocked into
pure black/white. So the idea of the green/yellow/red
filters is to lighten the leaves, darken the sky and
reduce the overall contrast of the scene (leaves vs
sky) - which then allows you to boost the local
contrast with increased development.
