That's an interesting series, and could merits its own thread to explore other examples. Your images all seem to have been in very high contrast situations, which can wash out colors and produce the appearance of blacks and whites where they aren't present visually. Often when I find myself in such environments I shoot for monochrome. You have used these factors as pathways to creative interpretations, and it works well especially in the final one where the two windsurfers are silhouetted against bright colored sails that are just about the only color in the images.
The first might as well be shot in monochrome as the contrast has rendered it that way for you. The middle one looks like it would make a nice monochrome as well; it is my favorite scene of the 3, a beautiful well composed and dramatic shot where the cloud seems to rise up out of a waterfall that's raging above your head. Thanks for sharing a fascinating set and hopefully starting an interesting conversation here.
