This paper on providing "oo-information" (= objective object-information) on cultural monuments and sites, based on 3D photographs is also a contribution of CIPA task group 3 to the 2013 CIPA Symposium in Strasbourg.

To stimulate the interest in 3D photography for scientists as well as for amateurs, 3D-Masterpieces are presented.

Exemplary it is shown, due to their high documentary value ("near reality"), 3D photography support, e.g. the recording, the visualization, the interpretation, the preservation and the restoration of architectural and archaeological objects. This also includes samples for excavation documentation, 3D coordinate calculation, 3D photographs applied for virtual museum purposes and as educational tools. In addition 3D photography is used for virtual museum purposes, as well as an educational tool and for spatial structure enhancement, which in particular holds for inscriptions and in rock arts.

This paper is also an invitation to participate in a systematic survey on existing international archives of 3D photographs. In this respect it is also reported on first results, to define an optimum digitization rate for analog stereo views.

It is more than overdue, in addition to the access to international archives for 3D photography, the available 3D photography data should appear in a global GIS(cloud)-system, like on, e.g., google earth.

This contribution also deals with exposing new 3D photographs to document monuments of importance for Cultural Heritage, including the use of 3D and single lense cameras from a 10m telescope staff, to be used for extremely low earth based airborne 3D photography, as well as for "underwater staff photography". In addition it is reported on the use of captive balloon and drone platforms for 3D photography in Cultural Heritage.

It is liked to emphasize, the still underestimated 3D effect on real objects even allows, e.g., the spatial perception of extremely small scratches as well as of nuances in color differences.

Though 3D photographs are a well established basic photographic and photogrammetric tool, they are still a matter of research and practical improvement:

– For example, multistage concepts for 3D heritage photographs, e.g., combining before and aft images and images showing different focus, daytime etc., as well as combining 3D imagery of different sensors and comparing 3D imagery with drawings etc. and even standards for exposing and processing 3D heritage photographs are only some topics for recent research.

– To advise on state-of-the-art 3D visualisation methodology for Cultural heritage purposes an updated synoptically overview, even claiming completeness, also will be dealt with.

– 3D photographs increasingly should replace old fashioned subjective interpreted manual 2D drawings (in 2D only) of heritage monuments.

– Currently we are witnesses of early developments, showing Cultural Heritage objects in 3D crystal as well as in 3D printings.
