Nothing remarkable, but I was taken with the brilliance of the blue and white in this approaching thunderhead. (Actually, the thunderhead, as such, boiled up after this leading edge of building clouds.) It was a bit eerie in that this and other shots looked just like the photos of nuclear bomb explosions -- scary. Still, I love the beauty and majesty of clouds such as these.

PS - nothing, except cloning out a small dust spot (oops, need to clean).
