For over 30 years he has been photographing for architects, interior designers, hotels and resorts, commercial real estate interests, product and furniture manufacturers and retailers. He started out working with notable Bay Area photographers Joshua Friewald and Jeromiah Bragstad in the black and white film era. Since then he has progressed from Ektachrome sheet film to high resolution digital cameras. Abraham still uses electronic flash extensively to light most interiors and objects. He believes that lighting gives accurate and predictable color, textured highlights and shadows that will show detail and print. He lights in such a way that even another photographer would have a hard time figuring it out.
