Step 3: Blending Modes & Dodging
Duplicate Layer 1 and set the blending mode to Linear Dodge (Add).
This adds even more contrast.
Create a new layer "Fills".
Starting with a large-sized brush, fill in the top corners and make sure everything except for the girl is black.
Switch to a white color and start filling in the missing parts of the girl. At this stage, it can be helpful to toggle the layer below "Fills".
While doing this filling, use a hard brush. This makes the job done a lot faster.
Another tip is to set the opacity of Background copy to around 35% and place it on top of the layer stack (this way you see what is not white and needs to be filled in).
When you are done brushing, you should have a picture that looks something like this. (Selection mask)
Open up the Channels palette and click the button "Load channel as selection". (shown at right)
Go back to the Layers palette and select the layer with the original photograph, then press Ctrl + J to duplicate the selection to a new layer.
Hide everything but the new layer.
