Podcast: Photomicrography of Gems, with Nathan Renfro

0 Plays

Posted 04/29/2021

It’s Macro Photo Week at the Explora blog and you’ll find many helpful articles and videos about the tools, techniques, and practitioners of macro photography. On the podcast, however, we go deeper than macro, like 1000x deeper—our conversation is with geologist, gemologist, and microscopist Nathan Renfro, of the Gemological Institute of America. Renfro is a renowned photomicrographer, and his images of the interiors of gems, with their unique inclusions and imperfect perfections, are stunning color abstractions of the natural world. With Renfro we speak about the art, craft, and science of photomicrography—using microscopes to make photos—and how he documents the inner life of a stone. Renfro got his start in gemology thanks to the collection of rocks and gems his grandfather, a miner from North Carolina, left to him. From this collection a fascination grew, ultimately taking him to GIA as a protégé of John Koivula, noted gemologist and author of the Photo Atlas of Gems series. Renfro himself has become one of the leading image makers in his field, and we discuss the tools and techniques he uses to create his work, including fiber optic lighting, focus stacking, and Differential Interference Contrast. We also discuss the surprisingly simple cameras that he uses, as well as the adapters, filters, and apps that enable his wonderful creations. We ask about the advantages that mirrorless photography holds for his craft, about the commercial and scientific applications of his work, and how traditional photography with a standard zoom lens has improved his understanding of composition and color, thus benefiting his photomicrography. Join us for this exploration deep into microverses, which are as complex and unique as any place on Earth or beyond.

It has been “Macro Week” at B&H Explora, and this week’s episode will put a nice bow on all the articles and photos we have published on the subject, with an overview of what type of macro photography lenses and systems are available. We begin this podcast talking with photographer Marc Silber about his new book Advancing Your Photography: A Handbook for Creating Photos You’ll Love, in which he provides a complete guide to get you from concept to completion. He stresses visualizing your image, gathering the correct gear to accomplish that, and walks the reader through all the steps of production, post-production, and exhibition. The tools he provides are apt for beginners. Enthusiasts—and even pros—will pick up a few tricks. After a short break, we continue the macro photography theme with a listing of the latest macro lenses available at B&H, and a practical conversation on what defines macro, techniques for improving your macro photography, and alternative methods for creating close-up and macro images.
