Shade and shadows, both things I enjoy capturing in my photos. So many choices, but I’ll start with the shadow of a shade (or blind if you prefer), just so I can use both terms in one shot, even if the “shade” part is different from what Ann-Christine is talking about.
Shadow owes its birth to light. ~John Gay

In the desert, there’s a serious side to shade. Here the shadow of a rock formation in Boyce Thompson Arboretum provides much needed and appreciated shade. The temperature difference, even in the early morning, can be quite a contrast and in some situations could even be a life-saving one. Walking along the shaded path was infinitely cooler than when that path wound its way into the full sun. Trust me. When temperatures start soaring over 100F, you’ll learn to love the shade!
To sit in the shade on a fine day and look upon verdure is the most perfect refreshment. ~Jane Austen

I’ll finish with perhaps my favorite shot of shade and shadow ,from the Visitor’s Center in Saguaro National Park. I shared it once before, but it’s so perfect for this challenge that I hope you’ll enjoy it again in this different context.
What is the purpose of the giant sequoia tree? The purpose of the giant sequoia tree is to provide shade for the tiny titmouse. ~Edward Abbey
