This is how it was created
1. Open file in ACR
2. Reduce green red slider to -85 (The D200 has magenta areas that can be annoying)
3. Set the white and black points using the PLOWDEN SHUFFLE.
This is a brilliantly simple fast way to set these points shown to me by our own Robert Plowden Esq. As follows...
Open Levels move Left (black) input slider to extreme right until everything goes black EXCEPT the whitest points. Using the white dropper click on the point you feel is the best white point. Then push the Right (white) slider all the way to the left so the screen goes white EXCEPT for the darkest points. Using the black dropper click on the point you want to be black. Clearly there is room for adjustment at this stage if you want a more contrast effect.
4. The resulting image has some patches in the 'white' areas that are still reddish Just remember that for now.
5. Using the channel mixer, switch red and blue levels to invert the colours.
(eg Red channel: Red -> 0%, Blue ->100% and Blue channel: Blue-> 0%, Red ->100%)
6. You now have inverted the red/yellows to blue/greens.
But you can still see that the patches in the white areas (mentioned in 4) are now blue. This is where personal taste comes in...they annoy me!
7. Duplicate layer and desaturate the bottom layer
8. Using an eraser at 50% - rub over the areas with 'offending' blue patches to taste.
9. Reveal the lower layer and flatten
10 Sharpen to taste
EDIT - Sorry cant seem to get this size file to be bigger on screen??????
Looking at the ramparts file above ...I clearly toned down the BLUE skies a bit before saving.
