I'm not in the market for a projector, but, i have this nagging question.
Having a background in photography (I taught at the university level prior to becoming an engineer), and knowing about color printing with inkjets etc.. How many colors to projectors project? Is there a future for projecting more colors?
I ask because of my photogtraphy interests. Color printing use to be three color using red, blue, and green. Black was created by exposing the paper to white light, and white was created by equal percentages of the three primaries. Then four color printing was developed for periodicals by adding black ink to the process. Current inkjet printers can use up to 8 colors (six colors and two levels of black). Are projectors heading in this direction or are they still at three colors?
