The picture you linked is a rather famous picture because it displays an optical phenomenon which has yet to be described. Notice the reflection of the sun in the lower part of the picture. Notice that the direct image of the sun is blocked by a thin upper cloud yet the bottom image is not obscured by this same cloud. This isn't a water reflection, and it's not a lense effect (the top cloud isn't reflected in the lower sun image). Some believe it to be a refraction effect, however this also doesn't explain the absence of the top cloud.
So nobody knows why the photo turned out the way it did. Maybe someone's explained it since last I heard.
