This is a negative environment for me because it is a social environment. It is easy to get distracted here by the many people walking by, eating, laughing, and also the smell of food sidetracks you from studying.
The perception of what we see is so different from each other, that the logical conclusion of all is in the subjective that every idea or thought ends up being.
I've always liked this picture, particularly how the lights all head towards the brightest spot of the sunset.
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.

Experiments in perception is a thesis project completed in Paul Sahre & Lindsay Ballant's portfolio class. It is a series of objects and situations that attempt to make others re-think the usual. It's over-arching goal was to test boundaries of logic, language, pre-conceived notions and social convention through the filter of design.
