Purchase sky backgrounds?
Every time I go out, I take a few photographs of the sky. Now I have a collection of over 2,000 high-resolution images, categorized by orientation, focal length, and weather. Didn't cost a penny.
Some of the best shots were made when I went deep sea fishing. Total sky with no interference by trees, power lines, buildings, etc.
