Shooting cloudy skies to the possible future need

Today was very clear and sunny day, and there were beautiful cotton-like cloud formations in the sky, so I decided to go to shoot some sky pictures to my picture archive. Those cloudy blue skies are excellent backgrounds, which you can add to portrait pictures taken in the studio or taken in otherwise bad or grey weather. I am also planning to increase my archive also some other kind of background stuff, such as forests, cityscapes etc.

Here are the skies I shot today, though converted to B&W.

Enjoy!
