What Is Dicyanine?

Dicyanine is a synthetic dye with a notable history in early photographic experimentation. Researchers utilized it to enhance photographic sensitivity in plates, including in efforts to capture stellar spectra.

Its more unusual association comes from Walter J. Kilner’s 1911 book, The Human Atmosphere. Kilner described observations using chemical screens and interpreted certain appearances around the body as a human “atmosphere,” commonly referred to as an aura. His findings became an enduring reference for those intrigued by unusual optics and perception.

It’s essential to note that photographic sensitivity and human vision are distinct. The use of a dicyanin glass in infrared photography does not imply that through a lens containing it, one can achieve infrared vision.

At Relic Holders™, our VOID-SEE™ collection draws on this rich history of optical inquiry. The MKII and MKIII models feature different lens arrangements and frame finishes, with each numbered pair coming with a hard case and a field manual.

Explore the individual product pages for details about each model’s construction, dimensions, contents, and instructions. Choose the edition that captivates you, and use the accompanying manual to guide your observations.
