Minolta RD-175

The Minolta RD-175 was one of the first digital SLR cameras. When Minolta introduced this camera in 1995 it did cost a very huge amount. At that time the Minolta engineers used a costly trick to get good coulour pictures in 1,75 mega-pixel resolution: The light which got through the lens had to be ripped into a red, a green and a blue light part. Ech part was projected onto an own CCD-light-sensor. So the camera included 3 sensor which worked together for making coulour pictures.
