Markus Brunetti

Mr. Brunetti, who was born in Germany in 1965, had worked for about two decades in advertising when, in 2005, he switched to a more singular vocation. He became an itinerant photographer of one of photography’s oldest subjects, the religious architecture of medieval Europe, and used the latest technology to capture the facades of these landmarks with an astounding clarity of detail.

Mr. Brunetti began traveling around Europe with his partner, Betty Schoener, and what the gallery calls “a self-contained computer lab on wheels,” making color images of cathedrals, churches and cloisters mostly from between the 11th and 14th centuries. The structures are very large, and so are the images — up to 10 feet tall.

The wonder lies in giving the eye more than it can see. The facades are recorded one square meter at a time, from a fixed position; then these tiny images — from 1,000 to 2,000 — are painstakingly stitched together. The final photograph has a bracing sharpness. Every feature is visible, from the narrative reliefs above the main doors to the gargoyles and spires high above, to the color and textures of the stone.
