During the 81 exposures used to make this photograph clouds began rolling across the sky in a north to south direction. I made a composite image without the clouds but decided to include them in the final image. I like how the clouds appear to originate from a "radiant" to the northwest. This image was made of 81 twenty-second exposures taken with a Canon t2i. Each exposure was 20 seconds, 800 ISO, f/4.5 using a Sigma 10-20mm lens at 10 mm. Two exposures were taken at the end focusing on the plants in the foreground, stopping the lens down to f/22 and light painting the field. All images were stacked using StarStaX.

The clouds add a nice texture to the image, and the light painted foreground
adds depth and framing. Well executed, Marion!
