Abstract 
New perspectives for Single Images in Conservation are permanently gained from dealing with the "4 point state of the art standards" 
for "taking", "processing", "applying" and "archiving" of images, including www access, as far as possible. 
Consequently the chapters of this paper follow this "4 point program", opening particular new perspectives and practical advises for 
using Single Images in Conservation: 
Chapter 1 deals with new perspectives for basics and for obtaining single images in conservation. It recommends a new definition for 
single images in conservation and deals with new historic aspects, like Hockneys' camera lucida and reports on experiences from 
using new sensors and platforms, like the Telescope Camera Light. 
Chapter 2 is on new perspectives for "processing" single images in conservation, including projection theory and algorithms, and on 
promoting the distribution of software for image rectification and mosaiking for both, sophisticated and simple solutions. 
Chapter 3 points to New Perspectives from using single images in conservation projects. It is reported on own experiences, offering 
new perspectives for the use of single images in archaeology but also on, e.g., the role of single images giving reference forjudging 
on the laser scanning resolution. 
Chapter 4 deals with New Perspectives for Archives for single images in conservation according to the truth, that an efficient 
application for single images in conservation will not work without a proper archive. 
1. New Perspectives for Basics in Single Images in 
Conservation. 
Cartography, Photogrammetry and Remote Sensing contribute 
to the inventory and to the Detection of monuments, as basis for 
further monument protection. 
It shall be pointed out, valuable documents for this purpose are 
in particular imaged local indications (see Fig. 1.1 and Fig. 1.2) 
historic maps and Photos, but handed down texts only with low 
priority. 
In addition, "quasi photographs", which are precise historic 
paintings in particular, mainly dating back to "ancient times" 
(before the invention of the photography) still contain treasures 
for conservation purposes. Namely this historic paintings 
showing proper perspective projection are obviously based on 
"Hockney's" camera lucida or comparable projection devices, 
which of course also have their tradition in Photogrammetry, 
like the well known historic Aero-sketchmaster, which is 
nothing else than the camera Lucida, see fig. 1.3:

"largest ever" Roman Treasure in Hildesheim (Germany), see
