Clearly a Fish, 2001

Photomacrograph made with a digital SLR camera system

This Cichlid fish, Paratilapia sp. (Cichlidae), measured 4 cm from nose to tail. The specimen was clarified and stained before submersion in a clear vessel filled with alcohol. It was then illuminated from three directions. Additional transmitted light eliminated shadows in the photographic setup.

Lavender Leaf, 1999

Scanning electron photomicrograph; x590 approximate magnification; post-capture digital colorization

The image shows a small portion of a leaf from a lavender plant, Lavandula angustifolia. Numerous dense branched hairs, called trichromes, are observed in the picture covering the leaf's surface. These hairs function as a protective barrier against the invasion of pests and also serve to reduce water evaporation from the leaf.
The rounded structure (pale tan, lower center) is an oil gland that produces lavender's aromatic scent. Below the gland is the impermeable cuticle that is supported by epidermal cells. The color in this image was digitally added afterwards since scanning electron microscopes are only capable of producing monochrome images.

Common Marmoset, Callithrix jacchus, 2000

Composite color transparency made with a macro camera system and light microscope

This image series shows a magnification progression of the Common Marmoset monkey from the whole body down through detail perceptible at the cellular level. The original intention was to photograph the whole fetal image; however, when magnified for closer inspection, the intriguing picture in the foot was observed. At a magnification of x12.5, the bizarre likeness of the face in one of the toes was discovered. The three images were combined to record this scientific oddity.

Lightning Strike with a Second Upward Streamer, 1987

Landscape photograph made using a time exposure of unknown duration at f/5.6; color transparency film

This strike was photographed on a hot August night during a thunderstorm in the foothills of the Santa Catalina Mountains that border Tucson to the north. This photograph shows two positive upward streamers, one that created a bolt on the left and a second upward streamer on the right that is unconnected.

Microbes in Basalt, 2000

Digital photomicrograph; illuminated with infrared energy and electronic flash; post-capture digital composite

Columbia River basalts from beneath the Idaho National Engineering and Environmental Laboratory were found to harbor 85 strains of soil-dwelling microorganisms. Researchers studied living colonies of the microbes in thin slices from unaltered basalt cores by using an infrared beamline at the Advanced Light Source of Lawrence Berkeley National Laboratory. This technique has produced spectacular success in establishing the role of microbes in detoxifying carcinogenic and radioactive pollutant waste areas.
The specimen was photographed through the courtesy of the American Museum of Natural History, New York.

Comet Hyakutake, Polaris, Big Dipper and Saguaro, 1996

Astrophotograph made using a time exposure of 12 min. at f/2.8; color transparency film

This photograph was made on March 27, 1996, in the Arizona Desert near Florence, Arizona. While the stars exhibit trails due to the rotation of the earth during the exposure, the Comet's head is relatively sharp because it was in close proximity to Polaris.
