Top-grade camera manufacturer Hasselblad has released its first digital unit. The DFinity was developed in collaboration with CCD developer Foveon. The camera is designed to get round the problems in capturing moving subjects found in most high-end camera backs and the artifacts encountered in images taken with standard single-chip digital cameras. The Dfinity includes three CMOS image sensors, which are mounted on a prism – allowing the camera to pick up full RGB information for each pixel. Hasselblad is working on optimized lenses for the prism-based imaging engine. For now, the camera can utilize Canon EOS lenses with an adapter. The Dfinity only works when plugged into a controlled computer as it is controlled onscreen by Dfinity CAM software, which runs on a Windows 98 machine that it connects to using an IEEE 1394 (aka FireWire) cable. It is possible to plug the Dfinity into a Mac, but it must be controlled from a Windows 98 machine networked to the Mac. A live colour video preview is viewed on screen at 1:1 of the final image. Users can automatically focus the camera by pointing the mouse at the required point and pressing a key. The camera also includes an auxiliary shutter for automatic dark calibration and sophisticated gamma correction that includes a film-like response curve for results that resemble conventional film. The camera also ships with Dfinity LAB software, which includes functions for image reviewing, tone reproduction control, and colour correction. It can also save TIFF or JPEG images at sizes up to 48MB with or without embedded colour profiles. This runs on Windows or Mac machines.
