The mill building at the long-abandoned Atolia Mine. When I visited the site 10 years ago, this building was still filled with complex separating machinery, offices, kitchenette and a wet lab. The entire interior is gutted now.
Once I saw the potential for symmetrically lining up the windows and concrete foundation inside, I made a long series of test exposures to get this ridiculously complex set up perfectly aligned. Then it became a question of balancing all the different lighting elements. Turquoise and red skimmed outside, green and purple inside. All lit with the Protomachines flashlight. Slight perspective correction in post, too.
