Heya all…matte/alpha problem

Hi all

Please could you all help me. I want to use the black and white picture of the women shopping as an alpha and use the cloth as a fill. From reading some posts here, I see i need to channel the black and white picture of the women into the alpha of the cloth and merge downstream…..right?

Please see my attached nk project and see where i am going wrong. There are 2 options there.

So 2 ways of doing this would be too use shuffle copy. I want to have the red background under the women with a fill there. …mine does not happen…i have tried to shuffle things around there and no luck

The second way is to copy a just the red channel like you can do with flame into the alpha channel…since the black and white has no colour the red channel is fine…Can this be done or am i barking up the wrong tree here?

Many thanks all
