    Question colour mixing

    can someone explain this to me please......
    if you have a blue 473nm connected to pins 7 and 20 and a blue 457nm connected to pins 8 and 21, how does the system know what analogue signal to use if you are making magenta by mixing blue and red ? in other words which blue diode to use ?

    i don't have a 457nm blue but would like to understand this ?
    thanks .........dave321

    Cool

    The software should use both. Assuming you are using a Pangolin controller, the balance will be adjusted when you go through the color balance calibration procedure. Then the software will calculate the proper color curves and use them to adjust the intensity of both lasers to get just the right amount of blue.

    Well, you've bought about the best controller there is on the market to get the most color out of your projector. When you get setup, just be sure to go through the palette wizard and take your time getting all the adjustments just right. It really only takes a few minutes to get it right the first time and the results are fantastic!

    Cool

    Yeah, I gotta agree with DZ on that. I'm still learning what this QM-2000 can do, but it seems every time I fire it up I learn something that makes me go "Oh wow... Cool!" The thing has some damn fine features...

    (Would you believe it took me over a month before I got around to color balance adjustment? And the next day I figured out how the geometric corrections worked... Now trying to learn masking!)
