Many small bubbles on sky blue background - stock photo

An underwater photograph of bubbles on a clear blue background. The bubbles are randomly dispersed. The bubbles vary in size with most being very small and a few being larger. The background is a translucent blue. The light comes from the bottom of the photo, making the bottom of the background very light blue, while the top is a darker shade. The water is free of any visible impurities. The bubbles seem to be largely concentrated in the upper right portion of the center of the photo, as well as the upper middle.
