Citadel

In case you are interested in what is going on here..... the original colours were dark stems against a pale blue sky. I didn't like the look of the dark stems - so I gave in did some heavy-handed processing instead of my standard Lightroom only routine. I don't have Photoshop, so I did this in Gimp.....split out the blue channel as a B&W image, inverted it and then added it on top a flat coloured deep indigo layer to add back some colour.

Done
