I can see its been on here before and I have read other sites but all the examples seem very long winded to me. I have just been converting colour to B/W in the Image>Mode in Photoshop, then back to RGB same menu Then I use levels to adjust how I need, for complicated pics I might have a double copy of the image on layers that i can 'burn' through to reveal a slightly different contrast. Thats it! Do i really have to go through all these channel mixing bits? Really? Here is an image I took recently on colour film, scanned to CD and I converted it using the above method. It also has a 4/0/-4 setting in the colour levels to give it some sepia rather than the blue it has in RGB Is it that off?
