The layers:

Here in mode Lab we have three layers but they are different, the first L which is a component of luminance, a component which is the range of colors ranging from red to green and b component which is the gamut from yellow to blue.

To see the layers open the window layers in the menu "window"-->> " layers " .
Select the layer L simply by clicking above it, your photo now in black and white.
Go to the menu "Image"-->> "Mode"-->> "Grayscale", a window opens and asks if you want to delete the other layers, confirm OK.
Now you have a single layer.
Go to the window layer and duplicate your layer (Ctrl+j).
Now change the layer type to multiply, You will now be able to play on the transparency of the layer to have the result you want.
