equivalent sinarback. In 1994 Leaf introduced an improved model, the DCBII, which included a live-video view, and in 1998 they introduced the 6 MP Volare. A complete camera system was constructed using the Sinar view camera system with a Sinarcam 1 shutter system which provided control of the live image, and an adapter plate was made to use the backs with Hasselblad cameras. Driver software generally required the use of an Apple Macintosh to operate the cameras. These systems were complex and expensive. They used custom controller cards (known as the "SCSI taxi"), and were 3-shot backs; a colored filter wheel inside the back rotated to take red, green, and blue exposures. Competition and evolution Competition soon came to the new industry. MegaVision in 1992 introduced their T2 back, which was a similar product; it also was a 3-shot unit with a 4 MP square sensor. MegaVision had been making digital photography equipment based on video technology since 1984, and the T2 had live video preview. Phase One was founded in 1993, and by 1994 was selling their StudioKit scanning backs. In 1998 Phase One launched the Lightphase. which was the first one-shot back that could compete with film in terms of quality. Resolution was 6 MP and the physical size of the CCD was full-frame 35 mm, however the back was designed to be used on Hasselblad 500-series cameras. Other early industry entrants included Jenoptik who produced products in cooperation with Sinar, Dicomed (a scanning back maker which closed in 1999), Better Light (the most prominent scanning back maker), and Kigamo. By 2003, Leaf had an 11 MP model, the Valeo, and Jenoptik/Sinar had the 11 MP Sinarback 43. several vendors had 16 MP models; Kodak produced the US$15,000 16 MP Pro Back Plus using their own CCD, Imacon made the ixpress 96, Phase One had their H20 and Sinar continued its camera back development from the 22, 23h, 43h and issued the 44H which when mounted on a macroscan unit delivered an image of over 1 GB in size with live image focussing using the Sinarcam shutter system. As of 2014 Phase One has a large market share with their own camera manufacturing and the IQ series digital backs that offer 80, 60.5 and 40MP resolution respectively. IQ180 and IQ160 both capture in full-frame 645 format. Mergers and partnerships During the first decade of the twenty-first century the
