out the best after a little PP ...

Lovely photo, excellent composition.
The colors really give it a kick, but there is so much fun stuff with the
composition it would be fun to see what it looks like in black and white.
How does the gold-n-blue filter work?
Larry, it's actually not too shabby in b&w if I may say so. But I think
it would look best printed in some exotic process like what Mark Roberts
was recently playing with. It just doesn't have enough life on the small
screen, if you know what I mean.

duChemin's article here ...

Now I assumed that, lacking this filter, I could probably get most of
the "goodness" from its effect by using a regular circular polarizer to
improve the scene's contrast (if necessary) then apply tints during PP
in ACR (or Lightroom) using the Gradient Filters tool. That tool allows
you to easily cover an area, like from the horizon up to the top of the
image, with a graduated effect. In this case I apply a blue tint to the
area roughly from sea level upwards and and a second gradient with an
orange tint from sea level down to the bottom. At the same time, in the
sky area I apply some extra contrast and Clarity.
In this shot I actually arranged the gradient over the water so it's
pretty quick and most of the water gets the full effect. I also added a
3rd gradient to reduce the brightness slightly toward the bottom to
focus attention on the middle third of the shot. I was able to take
advantage of the silhouetting to avoid too heavy and obvious a
colour-cast in the larger non-sea/sky areas.
David duChemin makes heavy use of this filter in his work, which is
gorgeous stuff, btw. I recommend a read of his book Within the Frame if
you haven't seen it.
I really appreciate your comments, Larry.
