For a 2012 print campaign for the Berlin Philharmonic Orchestra, photographers Andreas Mierswa and Markus Kluska photographed the insides of musical instruments.

The photos of the string instruments evoke intimate concert halls, with shafts of light illuminating perfect spaces in which you could imagine string quartets playing to small audiences. Inspired by their work, Romanian artist and photographer Adrian Borda has produced his own set of similar photos.

Free of the constraints of advertising, Borda’s images are a little grittier, reminding me less of tiny concert spaces than of natural rock formations like Arizona’s Antelope Canyon (and other slot canyons of the American Southwest), Petra, and the cenotes of the Yucatan in Mexico.
