Clear waters (720nm infrared)

That one is a 8:5 ratio false-color development (17802 x 11126px, 198,1MP, cylindrical arrangement) of this full IR panorama:

It is really easy to harvest the blue in water with the 720nm filter, yet by the same token often hard to clear it from foliage or clouds in order to get a balanced image. Under these conditions the dark infrared filter also kind of acted as a ND, so the water got smooth and silky (due to longer shutter speeds).
