Then the lightest sepia tone in my collection, adjusted to make it even lighter.
So apart from the sepia tone, nothing else touched the sky other than the normal levels work and the conversion.
Any suggestions welcomed. Am at work at the moment, so will explore this later when I get home.
ps - GIMP Users using GMIC : Anyone know if you have to desaturate first, before using GMIC B & W? Shouldn't have thought so, but .....That can't be it. The wall, grass, etc have converted okay .... haven't they!?
