What would be a good TRUE black and white colormatrix?

Question

I want to convert an image from color to B/W (i.e. no grayscale, just black and white). Does anyone have a good colormatrix to achieve this?

Answer 1

If you want it to look halfway decent, you'll probably want to apply some form of dithering.

Here's a full discussion, if a bit dated:
