History
The first commercial digital camera back was introduced by Leaf (now part of Phase One) in 1991. The Leaf DCBI (Digital Camera Back I), nicknamed "The Brick", offered resolution of 4 million pixels (MP) in a 2048×2048 pixel format the same CCD was used by Sinar in its equivalent sinarback. In 1994 Leaf introduced an improved model, the DCBII, which included a live-video view, and in 1998 they introduced the 6MP 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.
