Noon shadows or moon shadows.

So often photographers put their cameras away at midday. The warm light of dawn is gone and shadows shorten. For many, it's time to do something else until the sun gets low in the sky when the shadows lengthen and the warm light reappears as sunset approaches. But God gave us the sun to light the whole day and the moon to light the night so let's use them both while we have the opportunity.

For example, the sharp shadows of the wrist straps with their red keys wouldn't be the same at dawn or dusk. It's the short sharp shadows of the overhead light, whether sun or moon, coupled with the deep cold blue that makes this image work. After all, moonlight is only reflected sunlight, and great photography is all about managing the image before you with the light above you.
