Stephen retired from a rewarding aerospace engineering career with NOAA, NASA and the private sector where he led the design, development and operational deployment of real-time ground receiving systems and multispectral science data processing systems for earth- and lunar-orbiting remote sensing spacecraft. He now devotes more time to his long time hobby: nature and landscape photography.

Stephen has served as the Director, Assistant Director, and Education Coordinator of the Central Maryland Photographer's Guild. He has led classroom and in-the-field workshops on flower and birds-in-flight photography. As an instructor at Longwood Gardens, PA he guided workshop participants how to seek out, creatively compose and photograph foliage patterns, forms and textures. He has given technical presentations on: digital camera controls and settings; lenses and filters; numerical modeling of digital camera buffering architectures and memory card throughput performance when shooting action photography; lossy and lossless image data compression; and the impact of ISO noise and Shannon entropy on camera RAW image file size and 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, notably: The American Landscape: 2015 and OP 8th Nature's Colors Photography Contest; and the Maryland Department of Natural Resources (DNR).
