Gigapanoramas

HDR spherical gigapanoramas are panoramic images covering a full 360° view horizontally and 180° vertically with a resolution of at least 1 billion pixels or more in HDR (High Dynamic Range) technology, allowing the image to be displayed with a large tonal range – showing detail in both very bright and dark areas.

The process of making them involves taking the component photographs using a camera – a digital SLR camera and a specialised automatic panoramic head. The focal length of the lens and the number of photos depends on the target resolution required, with a minimum of several hundred photos per panorama. Postproduction consists in colour and density editing of RAW files and export of the photos to a specialised panoramic software, which on the basis of the content of the photos and using data from the position of the panoramic head, while shooting individual photos of the components, creates a panoramic image developed to a flat form, giving possibilities for further editing, i.e. setting of proper geometrical parameters (levels and verticals), density tonality, HDR parameters, elimination of mistakes made during automatic merging of the photos.

The image prepared in this way is rendered into a multi-layer file containing the HDR image and the images from which the HDR image was created, ‘weighing’ several tens of gigabytes. The final editing, which consists in removing minor errors of image connections, colour and density correction, fine-tuning the HDR effect, is performed in a dedicated graphics processing programme, and then the finished panorama is exported to a format that allows it to be viewed in any web browser.

We have completed more than 20 projects, digitising more than 1,000 exhibits

We wish to cooperate with owners of monuments of sacred and secular architecture who understand the importance of conducting digitisation processes and want to disseminate knowledge about their monument in an interactive and virtual form, in accordance with the WCAG 2.1 standard.
