Geological Digital Specimen Photography
Julian Gray, Executive Director
Rice Northwest Rock and Mineral Museum
Geologists constantly need to depict rocks, minerals, and fossils for presentations and publications. 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 who has experimented with stacking techniques and others to produce stunning images. Julian's specialty is photomicrography. His images have been published in mineral magazines and books.
The trip may be partnered with a July Friday night talk, so please check the schedule updates on the website and the July/August edition of the newsletter. More details to come...
