We will use two photos a night photo and a photo with a person in it. First we will cut out the person using the refine mask and after that we will copy and paste to the night photo, now we will double click on the layer that we pasted and we will add a color effect and make it black after that we will add some bokeh effect and we are done.
In this tutorial I will show you how to cut out a person in Photoshop using the Refine Mask. First select the Quick Selection Tool and select the person or object that you want to cut out. Be careful not to select areas that you can see thru. Now on the top menu you will see Refine Edge, select the tool and paint over the edges of the person so that the hair starts to show up and you are done you made a selection of the person now just press CMD+J or CTRL+J on Windows to make a duplicate layer only of the selection.
