UV reflected modified cameras for testing possibilities of this type of camera in remote sensing of planet Earth and other various fields. UV light is highly absorbed by many commonly encountered organic materials, yet is reflected by many inorganic materials like stone and metal. If these organic materials are on a surface with higher UV reflectance, the substances will often stand out more strongly than visible-light or near-IR images. Many materials look very dark when imaged with UV light. UV photography is also particularly useful at archaeological sites, where it can reveal artifacts or traffic patterns not otherwise obvious. This type of camera can detect artificial objects in snow cover, UV protection glass, oil in water, fresh paint, sun milk...
