Early Photography's Scientific Reach: Lunar and Underwater Photography — Anika Burgess — Burgess explores early photography's critical scientific applications, noting that François Arago predicted the daguerreotype would enable detailed mapping of the lunar surface. Early astrophotographers encountered formidable technical challenges involving distance calculations, celestial motion, and insufficient ambient light. James Nasmyth controversially photographed plaster casts and molds of the lunar surface, which contemporary observers praised as scientifically truthful. Burgess also highlights Louis Boutan, who persistently developed practical underwater photography using pressurized hard-hat diving equipment, establishing a new scientific capability. 1865
