This is a photograph of Spring Lake, New York, not the Portuguese event site.
Changes: central bank cropped from source rectangle (1250,1300)-(6100,1740); connected foliage mask removes sky; reduced to 3880x352 at native aspect ratio; horizontally mirrored to place the lower bank beneath the sunrise. The website applies changing illumination and a softened water reflection.
