A new image sensor gives CCDs and CMOS a run for their money.
From pixel to paper
Capturing images on a sensor is only the first step in digital photography. Most shutterbugs want a hard copy of the photograph. This is where printers enter the scene and the need to reproduce stable color images. A lot of work has been done on archival-quality papers and chemicals. The best quality laser jet prints on archival paper are said to last up to 60 years, based on accelerated test conditions. To simplify the printing process even further, a group of camera and printer manufacturers have proposed a standard for connecting printers directly to the camera, bypassing computers all together. The proposed standard, dubbed DPS for direct-print service, would use USB1.0 as the physical layer and the Picture Transfer Protocol (PTP) as the standard for image-file transfer. Future versions may even support protocols such as wireless LAN.
