Retired from a rewarding aerospace engineering career developing information systems for earth-orbiting and lunar-orbiting remote sensing spacecraft, Stephen now devotes more time to his long time hobby: nature and landscape photography.

He has served as the Director, Assistant Director, and Education Coordinator of the Central Maryland Photographer's Guild.

Stephen has led classroom and in-the-field workshops on flower and birds-in-flight photography. As an instructor at Longwood Gardens he guided workshop participants how to seek out, creatively compose and photograph foliage patterns, forms and textures.

He has given technical presentations on: lenses, filters and optics; camera controls and menu settings; quantitative modeling of in-camera buffering and memory card throughput performance for action photography; lossy vs. lossless image data compression algorithms; and the impact of ISO-induced noise and Shannon image entropy on camera RAW data compression efficiency.
 

Diana, my wife and photography partner, and I catalog and post processes our photographs. Diana is self-taught and initially honed her skills using Photoshop CS3 to restore vintage 35 mm prints. We use Adobe's Lightroom Classic and Photoshop and post processing products from Topaz Labs. Our work has been published by Outdoor Photographer (OP) magazine: The American Landscape: 2015 and OP 8th Nature's Colors Photography Contest; and the Maryland Department of Natural Resources (DNR).
