Clear back in October, Lenscratch had an article in their Art + Science series on the body of work by David Shannon-Lier titled Of Heaven and Earth. The first image in the article, Chalk Moonrise, Muley Point, Utah, pulled me in, since I love long exposures of the moon and sun, but also, there was more to the image than just the long white arc of the moon as it traveled across the sky: on the rocks in the foreground is a light line that matches the radius of the moon's path. 

Not only are these absolutely gorgeous photographs, but the concept behind them is so fun and interesting! 

In a LensCulture article, Lier says this about his work:

To produce each photograph, I leave open the shutter for a very long exposure. The result is an image of the moon or sun playing off of an altered landscape. In this way, the heavenly meets with the human, the immense with the intimate and one of the most constant forces in our world—the movement of the solar bodies—interacts with a line of rocks or grass: a mark that is small and completely fleeting in meaning and form.

To see more of Lier's work, which I highly recommend, you can visit his website. Also, he's been featured on LensCulture, Fraction Magazine, and Hoctok.
