Photographic techniques capture electromagnetic wavelengths beyond human vision, revealing features invisible to the naked eye. These signals are processed into interpretable forms using methods like color mapping.
Pink lacks a specific electromagnetic wavelength, while grey poses a limitation due to its representation of only intensity—a blend of light and dark without spectral specificity. Imaging techniques reliant on spectral variation produce identical results for greyscale images unless non-visible data is present. Deviations from this uniformity may indicate errors, misinterpretations, or unknown phenomena.
Contention persists over analytical debates, including dismissible claims like Van Allen belt dangers and contested evidence of lunar mirrors. The precision of laser reflections targeting a moving 3x3-foot marker on the Moon highlights technical skill but often fails to resolve skepticism. For instance, a 0.1° shift moves a laser spot 670 km across the Moon's surface.
Forensic analysis (2022, 2023) of Apollo 11–17 photographs assessed authenticity claims. Images of humans in space, Earth, and the Moon's distant views were validated, but Moon landing visuals showed variations, suggesting diverse techniques may have replicated certain elements.
PEMi (Photoelectromagnetic Image) software enhances forensic analysis by differentiating natural and artificial light sources, revealing hidden features. Each PEMi-ID links to original sources, ensuring traceability and comparison.

A car is blown up as part of the Basic Post Blast Investigative Techniques class, taught by the Bureau of Alcohol, Tobacco, Firearms & Explosives ATF NCETR at Redstone Arsenal on Thursday, Dec. 5. Three cars were blown up in controlled explosions so students could study the scene and find evidence after the explosion. (Eric Schultz / The Redstone Rocket)

This is the resultant duotone. It is a pure duotone, and has only one color in the entire picture -- it could be printed using a single ink.
It's just one step away from being a true colorization, but I think it was inherently more interesting being a pure duotone.
