(I assume a basic knowledge of Photoshop for this tutorial.) The way that I created the image above is basically just combining three images into one using blend modes and opacity changes. Here is how I did it (Due to my blog theme, you may need to click on each picture to see them clearly.): Take your model image and cut her out using the pen tool:
After you finish the selection, right click on your mouse (still inside the pen tool)
When you see the marching ants, maneuver to the quick selection tool, right click on the image and click ‘Select Inverse’:
Marching ants will appear around the model and around the entire image as well:
Unlock the layer and press ‘Delete’ on your keyboard.
Now press ‘Ctrl + d’ on your keyboard (‘command + d’ on Mac) to deselect the image. Click the File menu and click ‘Place Linked…’:
Choose your image. Here is mine:
Now that it’s placed, move the model layer atop the city layer.
Now, right click on the city layer and click ‘Duplicate Layer’:
A box will appear. Name your layer and click ‘OK’:
Click on the model layer in the layers panel to activate it. Click the quick selection tool and select the model in marching ants once more.
Put the duplicate city layer atop the model layer, turn off your original city layer and click the city duplicate layer in the layers panel to activate it.
Right click on the image and click ‘Select Inverse’.
Press ‘Delete’ on your keyboard. You may see this error:
If you do, click ‘OK’ and right click on the city layer to rasterize it (this may not be necessary for you. If the option is grayed out, skip this step.).
Click the city layer and shift click the model layer to activate them both.
In the drop-down menu just above the layers, select ‘Multiply’:
You will see this:
A box will appear:
Brightness = 25 Contrast = 100 Repeat the adjustments step once more except not adding more brightness. Next, place the sky. File>Place Linked. Choose image and here is mine:
Arrange layers as below and turn on the original city layer:
It should look like this:
Click on the sky layer to activate it and turn the opacity down to 35%:
Click on the duplicate city layer and turn the opacity down to 65%:
You should have this:
Now, time to retouch the sky and model. Click the model layer to activate it and go to the Filter menu in the upper left corner and click ‘Camera Raw Filter…’:
Click the adjustment brush:
Here are my adjustments:
Now, for the sky. Click the sky layer to activate it and go to the Filter menu in the upper left corner and click ‘Camera Raw Filter…'(NOT THE TOP CHOICE ‘Camera Raw Filter’ that is adding the same adjustment as last time):
Select the first menu and click ‘White’ in the menu and click ‘OK’. Now, click on the original city layer to activate it and and set its opacity to 75%.
