Question black and white with channels red,green,blue how?

Hi

can i create a black and white using & take advantage of channels red,green,blue ?

in short i would like to make a black and white and take advantage of my red channel and green channel and blue

i tried without luck

what i did
1) load an image
2) channel palete -> copy my red , green and blue channels
3) add a channel mixer monocrome-> apply image ->layer channel(channel mixer) ->channel red copy
4) add another 2 channel mixers monocrome with green and blue masks

in short i have
1) the original image
2) adjustament layer channel mixer + red copy mask
3) adjustament layer channel mixer+ green copy mask
4) adjustament layer channel mixer + blue copy mask

but the image is still not black and white


sorry for my poor english but i would create a black and white take advantage of my red channel and green channel and blue , using my red ,green and blue like masks

what's wrong?
is there a way?
i tried to find a video on you tube without luck

thanks

There can not be, because noone has your image.

It's all about the starting point. If you post your image and example of what you would like it to look like, we might be able to help you.

Not a video but this should offer some insight in using channel mixer plus other methods to produce B&W
