Julian Gray will be presenting “Digital Specimen Photography for Geologists,” a presentation on macrophotography and photomicrography, the photographing of things at the microscope level. The event will be at the Portland State University as part of the Geological Society of Oregon Country events.

Digital photography has extended the range of possibilities in illustrating samples. One common problem, reduced depth of field at high magnifications, is easily overcome using stacking techniques. This technique uses sharply focused portions of sequential photographs focused on different slices or stacks to produce a synthesized images in which the subject is crisply focused.

Julian Gray, executive director of the Rice Northwest Museum of Rocks and Minerals, is a geologist and semi-professional photographer specializing in photomicrography. He has experimented extensively with photographing through microscopes and using stacking techniques and others to produce stunning images with extensive depth of field, bringing sand, crystals, minerals, and even salt to life and shine like diamonds. Julian’s images have been published in mineral magazines and books. He is also the co-author and contributing photographer of the upcoming book, Minerals of Georgia.
