Imaging Setup & Techniques

All of the images in this article were photographed using the Nikon D300 camera, Nikon P bellows, and Zeiss objective lenses, ranging from forty to sixty-three millimeters in focal length. The imaging system was mounted to a copy stand, while the subject (grown on agar and encased in a petri dish) was elevated with a lab jack covered with a black velvet piece to use as a background. A set of fiber optic lights were used to illuminate the subject, specifically the individual colonies.

About the Photographer

Dina Yang is currently an undergraduate student studying Biomedical Photographic Communications at the Rochester Institute of Technology (RIT) and expecting a Bachelor’s of Science in May 2011. She has completed her photographic concentration in high magnification photography and ophthalmic photography. Ms. Yang has done various cooperative work studies involving the two different types of photography at places such as the New York Eye and Ear Infirmary (New York, NY) and the Albert Einstein College of Medicine (Bronx, NY). She is currently involved with research with Robert C. Osgood, Ph.D. from the College of Science at RIT, examining different bacterial species involved with cathether associated urinary tract infections (CAUTI), two of those species examined being S. agalactiae and S. mutans. If there are any questions or comments regarding the images, please feel free to contact Dina at and visit to see more of her work. For more information about the research project, contact Dr. Robert Osgood at
