Nightscape Photography: The Juxtoposition of Earth and Sky

Robert Arn

Explore the world at night through your DSLR camera. Juxtapose wide open meadow, towering mountains, and vast deserts under the Milky Way. In recent years, consumer-level sensor technology has opened the possibility of capturing images in very low-light conditions. We will combine common landscape photograph techniques with those used in more traditional forms of astrophotography to tackle the challenges of imaging the world with the sky at night.


Robert Arn has spent more than 10 years in the field of astrophotography. He synthesizes his love for astronomy and photography into the beautiful world of nightscape astrophotography, the art of juxtaposing the Earth with the night sky. Never was a person happier spending long nights on a secluded mountainside beneath a blanket of stars in subfreezing temperatures with a camera in hand. Robert shares his love of this unique form of photography by his involvement in public outreach. He has hosted astrophotography workshops through AstroArn Photograph and the Loveland Photographic Society and has taught astronomy courses through Colorado State University as well as at a number of outreach events and star parties. He has given numerous astrophotography talks along the Colorado Front Range and central Illinois. Robert's work has been showcased and published in a number of settings, including NASA’s APOD, URSA’s EPOD, Les Cowley’s OPOD. He has also given talks about the mathematics of image and video processing. Robert enjoys the challenge of constantly learning new and more advanced photo processing techniques to add to his growing toolbox for astrophotography, drawing from both the skills he has developed in astronomy and those in photography. In addition to astrophotography, Robert received his PhD in Mathematics at Colorado State University in 2016. He currently works as a Software Engineer at Northrop Grumman in Denver/Aurora, CO. His research is in image processing, video processing, optimization, machine learning, large data analysis, geometric data analysis, and large data analysis. When he is not working, he can be found on the side of a mountain or underneath the stars, trying to capture part of this majestic universe.
