Between color and black

First I did (Layer>New Adjustment Layer>Channel Mixer).Then I clicked to check the box that says Monochrome to make the picture black and white (but don’t click OK yet). You may want to adjust the weights of each color in the black and white configuration depending on the picture, then when it looks good to you click OK. Then make a duplicate of your first layer (the layer containing the picture, not the adjustment layer). Make sure you have the right layer selected when you try to make the duplicate (Layer>Duplicate Layer).Then while you still have that layer selected, change its mode from Normal to Overlay. You will have a nice picture if you follow these steps.
