Xeroradiographic imaging

Article Abstract:

Xeroradiography is a radiographic imaging technique which produces an image by virtue of the different charge densities of a selenium plate and a conventional X-ray source. The technique has been used in many studies because produced images are easy to interpret and understand. This, in turn, is caused by a halo effect that enhances the edges, joints or pores in the image. Xeroradiographic imaging has been used in examining a ceramic rhyton of a gazelle head at the Smithsonian Institution.

Low-altitude photography

Article Abstract:

Archaeologists employ low-altitude photography in their work. Using photographic balloons at heights of no more than 800 feet, archaeologists take vertical pictures of excavations, thus preserving valuable visual information. At present, archaeologists are experimenting with various camera systems to make low-altitude photography better. The technique was first used in 1931 at the Megiddo excavation.

Bird's eye view of the ancient world

Article Abstract:

Aerial photographs are of great use and importance to modern archaeology. Balloons are uniquely appropriate for archeological aerial photography, providing a steady platform without threatening fragile sites or obscuring the view. Eighteen photographs are included, many from the 1992 book, 'The Aerial Atlas of Ancient Crete.'
