Lance Keimig is best known for his night photographs, which are often made at the juncture of the built and natural environments. His book, Night Photography- Finding Your Way In The Dark was published by Focal Press in August of 2010, and has been translated into 6 languages. A revised and expanded second edition was published in July of 2015.

He has taught at the New England School of Photography in Boston since 2000, and has also taught at the School of the Museum of Fine Arts in Boston, The Photographic Resource Center at Boston University, The Houston Center for Photography, and leads independent workshops across the country.  Russell Brown, senior creative director for Adobe, said that Keimig may well be “one of the finest photography instructors on the planet.”

Keimig is a frequent speaker and workshop instructor for photographic events around the country. He has presented and taught at the Photo Plus Expo in New York, and was a featured speaker and workshop instructor at Estudio Brasil in Saõ Paulo, Brazil. He has lectured and taught for the Scottish Photographers Association in Glasgow, The School of Visual Arts in NY, B&H Event Space, and The New England Camera Club Council among others. 

Keimig continues to teach night photography and light painting workshops around the country, and also leads photo tours to Iceland, Ireland, Scotland, and Cuba. His work has taken him to such far flung places as Zimbabwe where he did documentary photography for a medical mission, the Philippines to photograph a museum collection, and Japan where he photographed Buddhist temples. His photographs are held in numerous collections including The Art Complex Museum In Duxbury, MA, The Boston Athenaeum, The Boston Public Library, and the The Grace Museum in Abilene, TX.
