Research and development


Haltadefinizione LAB® is constantly searching for new technologies for the study of cultural heritage.

In the digital information age, Haltadefinizione LAB® creates tools which allow to commit to eternity the splendour of the works of art that have come to us and that, because of their physical nature, are bound to deteriorate over time. Tools that do so without causing any damage to the work of art in question.

Such an approach, driven by a constant focus on excellence and innovation, aims to offer top-quality services for the conservation, restoration, and - in more general terms – the promotion of artistic historical heritage.

Imaging Technologies


Real High Definition

The RHD (Real High Definition) technology allows to achieve a resolution ranging between 1500 and 4000 ppi the original size. It is particularly suitable for the imaging of works/materials of a limited size to capture details that would be almost invisible to the naked eye.
The images obtained through this technology can then be printed out and enlarged up to 5 times their original size without any definition or quality loss.

Large High Resolution

The LHR (Large High Resolution) technology allows to achieve a resolution ranging between 300 and 1000 ppi the original size. It is the ideal solution for the imaging of large-size paintings, cycles of frescoes or, in general, paintings whose size does not allow to apply the RHD technology. This imaging technique applies powerful optics capable of capturing details that would not otherwise be visible to the observer.

Dispositivo Ripresa Codici

The DRC technology allows to create virtual copies of manuscripts and ancient codices, thereby making it possible to safely consult even the most delicate materials. Haltadefinizione LAB® has developed a special, non-invasive imaging device which, thanks to a special lighting system, can be used to perform digital acquisitions in frontal light, grazing light and back light conditions.

Virtual 3D Light

Haltadefinzione LAB® offers the opportunity to build photographic sets for imaging using the “Virtual 3D Light®” mobile light. The movement of the light across the room, together with the subsequent software processing of the images acquired, allows to obtain a mathematical model capable of reproducing the 3D features of the subject within a virtual space. Thanks to this tool, the 3D details of drawings and paintings (such as engravings and reliefs) can be virtually analysed without any additional impacts on the original materials.

Digitisation of documents

Haltadefinizione LAB offers ultra-high definition scanning services for the conservation of the information found in manuscripts, parchments and drawings - including large formats - using professional scanners. Haltadefinizione takes care of every single digitisation step: from flawlessly safe imaging to the organisation of the acquired material in multimedia platforms for subsequent consultation. Every project is tailored to the customer’s needs.

Care and safeguard of the artworks


Haltadefinizione LAB®’s approach to the imaging of highly valuable works is based on ensuring the greatest possible care for the paintings and frescoes, especially as regards the prevention of any potential damage caused to the work surface by the use of flash and lighting in terms of both light and heat.

The digital acquisition tools used by Haltadefinizione LAB® for applications within the visible spectrum meet the strictest standards in place for the preservation of works of art.

The LHR and RHD imaging techniques have been developed in close cooperation with Istituto Superiore per la Conservazione e il Restauro (the Italian Institute for Conservation and Restoration), which certified their fitness for purpose.

The Institute’s Physics Laboratory has performed a series of studies on the physical interactions between the imaging systems and the original materials. Results show that the stress exerted on the painting surfaces – in terms of physical, photometric, and micro-environmental parameters - is extremely low, almost at the threshold of instrument sensitivity.

The lighting system has been designed so as to minimise the area exposed during every single click thanks to a special pointer, while the use of filters allows to eliminate unwanted UV components. Under no circumstances is there any direct contact with the work’s surface.

Services for the cultural heritage sector


PUBLISHING SECTOR

Do you need to publish a book featuring unique details? Can’t you find the right images for your prestigious publication?
Haltadefinizione LAB®’s special tools and qualified staff will help you perform ultra-high definition “customised” digital image acquisitions. Thanks to a close cooperation with curators, publishers and graphic designers you will obtain the ideal images for any and all publishing projects, from prestigious books to exhibition catalogues.

CONSERVATION AND RESTORATION

Are you a public or private body in charge of the preservation and protection of works of art?
Haltadefinizione LAB® carries out digitisation campaigns for pre- and post-restoration documentation purposes. Unique images allowing to plan conservation activities and monitor the preservation state of works of art. Haltadefinizione LAB® also makes available tools for image consultation and actively cooperates with restorers and curators in the organisation of the documentation acquired.

Diagnostics

Haltadefinizione carries out multi-spectral digital image acquisition campaigns for the diagnostics and study of works of art. Besides ultra-high definition imaging, it is indeed possible to perform investigations through IR (infrared) and UV (ultraviolet) digital acquisitions.

Haltadefinizione LAB

Haltadefinizione® LAB develops technologies for the ultra-high definition digitisation and the diagnostics of works of art ensuring outstanding results in all image acquisition conditions with a wide range of cultural materials, from small paintings to large frescoed walls, all the way to manuscripts and ancient documents.

Technological partners


Haltadefinizione LAB’s disposal the best equipment and technologies available on the market.

All the equipment used for ultra-high definition digitisation is the result of the most advanced levels of research in the field of panoramic photography and technology applied to cultural heritage.

Hardware support for data management is also vital: Haltadefinzione relies on leading experts in this sector, who share its passion for excellence and innovation.
