Technical Data


For digitisation we are using a KODAK PROFESSIONAL DCS Pro SLR/n camera, that is, a 14 megapixel digital SLR camera, with Nikkor AF 50 mm f/1.4 normal lense, a Sigma EX 50 mm f/2.8 interchangeable macro lense and, for other purposes, Nikkor AF 28-105 mm f/3.5-4.5 zoom lense. This technology permits us to make high-resolution images (14 megapixels) with great photographic fidelity, because the camera works just like any professional analogue camera, using Nikkor and Sigma lenses. We are saving the images in a camera-specific (DCR – Kodak’s proprietary file format) and a general (DNG – Digital Negative, developed recently by Adobe) file format. These raw file formats ensure that all the basic settings of the camera and the properties of the image files can conveniently and without any loss of data be modified at any time, as if on the camera itself at the time of shooting. They are and hopefully will remain compatible with any existing or future operational system.
