Rayleigh Scattering refers to the scattering of light off of the molecules of the air, and can be extended to scattering from particles up to about a tenth of the wavelength of the light. when we look far away from the top of a building it is easy to say the far the things are, the more bright and blue they are, ans this is because of the water particles in the air and how the light affect them. In the images above I learn a way how to make this effect and make a pictures look that they have different depths. For example look at the picture and the first ship it has more contrast than the others, and this goes on. The second picture looks brighter and with less contrast. By making this effect, someone can tell each ship has a significant distant between them, and because the cliff itself has this effect, it looks like the ships are part of the image. I thinks the Rayleigh Scattering effect we never pay attention to it but it's always there. Before knowing this I technique, I used to place images without adding the Rayleigh Scattering effect so they looked as a plain image without any type of depth.
