My elevation when the pic was taken was about 640' ASL. Probably not.an issue. I took the shot less.than 10 minutes after.the sun had cleared the horizon and I was pointing quite a bit South of East and I exposed for the light on the sails which would have tended to underexpose the background.
The image here shows more green in the blue than I see on my screen with the full resolution, un-uploaded image.
Part of it is the nature of Kodak Ektar 100. Super fine grain, almost nonexistent in the 120 film here but it tends to really saturate colors, one of the reasons I wanted to try it.
