Nevertheless, such special prototypes are far from becoming an accessible option due to their high complexity and cost. The AWARE 10 and 40 models reach almost 3 Gp. This prototype included 98 micro-cameras with a combined resolution of 1 Gp and it is still being developed and improved. Another more recent proposal is the AWARE 2 gigapixel camera, started by D. In this bulky camera, the image was exposed on a 450 × 225 mm negative film, which was later digitized to form a 4 gigapixel (Gp) image. One of the first was the large format camera developed within the Gigapxl Project by Graham Flint in 2000. In fact, there have been few attempts to develop prototype cameras providing gigapixel images on the fly. Going beyond this would not take advantage of the effective resolution of the sensor, unless the size of the optical-sensor assembly were increased, which is not practical for the future development of conventional cameras. For this reason, the progression in the resolution of digital sensors has already reached the limit established by the diffraction of light and by the optical resolution provided by the lenses that cannot match the resolution of the current top digital sensors. The results will be disseminated through the Internet, as will be shown with some examples.ĭigital photographic capture with gigapixel resolution is not an easy task and serious difficulties may arise due to physical problems such as the diffraction of light, which represents a barrier that limits the sharpness that can be obtained with an optical device and a digital sensor. The result of this research work consisted in the gigapixel documentation of several masterpieces of the Museo de Bellas Artes of Valencia, one of the main art galleries in Spain. #Zoomify openseadragon series#This article describes a series of photographic methodologies and equipment, developed by the team of researchers, that have been put into practice to achieve a very high level of detail and chromatic fidelity, in the documentation and dissemination of pictorial artworks. #Zoomify openseadragon professional#Since today’s professional digital cameras provide images of around 40 megapixels, obtaining gigapixel images requires some special capture and editing techniques. Therefore, this kind of virtual visualization using gigapixel images has become an essential tool to enhance cultural heritage and to make it accessible to everyone. ![]() These virtual visualizations allow the viewer to delve into the artwork in such a way that it is possible to zoom in and observe those details, which would be negligible to the naked eye in a real visit. The results can be disseminated through online virtual museum displays, offering a detailed interactive visualization. This line of research is extremely interesting, not only for art curators and scholars but also for the general public. Digital photographic capture of pictorial artworks with gigapixel resolution (around 1000 megapixels or greater) is a novel technique that is beginning to be used by some important international museums as a means of documentation, analysis, and dissemination of their masterpieces. ![]()
