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.

This is one of the more informative and hands-on practical episodes of the B&H Photography Podcast that we have produced in some time. Obviously, it helps if you are “practicing” car photography, but the insights provided in this episode are useful for a wide range of photo disciplines, and touch on techniques for making better images of moving objects, reflective and non-reflective products, tight interiors, and how to photograph large items in a studio or on location. For this wealth of information, we must thank photographer Nate Hassler, who joined us to talk about his extensive work photographing cars, whether for advertising, editorial, or for personal projects, a.k.a. fun. Hassler is accomplished in each of these areas, and his advertising clients include Toyota, Honda, Lexus, and Mercedes. He is also a respected motorsport photographer, with work appearing regularly in Road & Track magazine. We find out that Hassler grew up around photography, helping in his parents’ photo studio, but developed a love for cars all on his own and seems to have found the perfect career that blends his two passions. We learn a bit about the automobile advertising business, but mostly we discuss capture technique, including the rigs and gear he prefers, shooting moving vehicles, stabilization, bracketing, back-lighting, lens distortion, and post-process. This truly is an educational and entertaining episode, and check out the B&H Photography Podcast Facebook Group for an image of Hassler’s “Franken-Instax” camera that he created to make instant photos with a Schneider lens.

Today’s episode broadens our normal photographic sphere as we discuss ophthalmic photography and how the eye’s own optical system is used in conjunction with camera equipment—some techniques very common, some not so—to examine the interior of the eye and to diagnose illnesses that go far beyond problems with vision. We are joined by Mark Maio, clinical medical and ophthalmic photographer and developer of the first high-resolution digital imaging system in ophthalmology. We talk with Maio about his early interest in social justice photography, working as a “jack-of-all-trades” photographer for a hospital, and how his eventual concentration in ophthalmic photography led to early adoption of digital technology and the development of a tool that helped to transform the industry. Throughout this conversation, we learn about the use of analog and digital photography in the biomedical field and how fundus cameras and other specialized gear are used to diagnose optical and systemic maladies. When the pupil is dilated, they eye becomes a portal into the body, and with the proper tools, we can see inside our corporeal system without cutting. Maio is also an accomplished fine art and documentary photographer, and we will also discuss how these various disciplines have intersected throughout his career and resulted in the workshops he leads on ophthalmic imaging, documentary, and landscape photography on the beautiful Isle of Skye.
